Image ModifiedzBASE Quick start guide

Getting familiar with a new piece of software is often tedious and sometimes daunting. To provide a Quick demonstration to those who are new to zBASE, this Quick start guide is a short tutorial aimed at providing a rapid introduction to the system.

...

This guide is no substitute for reading the manual. Indeed, this guide will merely scratch the surface of zBASE capabilities. However, since zBASE needs liveware to make use of those capabilities, it is important to the authors that the liveware should feel some early reward for the effort of getting familiar with zBASE. Those rewards are plentiful in this guide.

With the INDEX on display on the Z88, open the clear perspex cover labelled '1 2 3', and insert the zBASE Application ROM in slot 2. Close the perspex cover. (See the Fitting & Using the ROM.)

The menu bar should be moved on the APPLICATIONS INDEX until it is highlighting the zBASE application.

Press to run zBASE.

Image ModifiedQSG2

When the } symbol, known as the curly prompt appears, type the word QUIT followed by . This action ends the use of zBASE. In version 1.2 you need to confirm the return to the APPLICATIONS INDEX, by pressing any key.

This is the only proper way to exit from zBASE. If the  key is used, and the zBASE suspended application is KILLed, open database files will not be properly closed and permanent damage will occur to the data files.

Image ModifiedQSG3

The first real job is to create a data file. To do this, the file structure must be defined. This definition is done in PipeDream. Highlight the PipeDream application and press . This creates a new PipeDream suspended application.

Image ModifiedQSG4

Type in the following lines, exactly as shown.

...

Now press FS, followed by the file name, PHBOOK.DEF. Then move the cursor down 4 lines using the ò, to the question, 'Save plain text'. Enter a Y for YES and hit .

Data input

After creating the file, the next step is to enter data. To begin with, the method shown will be the simple way of storing information. QSG13 below sets out two examples of how command files can make such work easier.

With at least a few records entered, a FIND process is required. This may be done directly at the curly prompt, or as for appending, by means of a command file as described in Indirect variables.

The zBASE command to use on an index file is 'FIND'.

...

Note that only the first FOUR characters of any command need be used.

Type or load the program labelled PHENT.PRG96010404. Do not use  characters. The lines that start with an ASTERISK (*) are comment lines that are ignored by zBASE. They do not have to be typed in at all.

After typing in PHENT.PRG it should now be saved. Press FS, enter the filename PHENT.PRG,  4 lines and enter Y to save the file as PLAIN TEXT.

Back in PipeDream, after the file save, enter W to return to zBASE. When back at the } prompt, type the following

...

[If zBASE was QUIT rather than left suspended, the database file with its index must be re-opened before running PHENT.PRG. If this is the case, see QSG9 above for guidance on re-opening the file.]

This quick start guide has been designed to provide new users with an opportunity to get something out of zBASE quickly. It does not reveal the flexibility available in zBASE nor does it demonstrates the wide potential for this database management program. The rest of the manual does go much further into the commands and functions contained in zBASE. Please take some time to review the rest of the manual and so enjoy the further capabilities of your Z88/zBASE combination.

Image ModifiedzBASE Manual

The Quick Start Guide is designed to be a brief exposure to the major facilities of zBASE. Those new to database languages may find this a very useful starting point.

Section A of this manual, 'Introduction to zBASE', describes zBASE in descriptive terms with some examples of how the system can be used. Commands are dealt with in an order that are likely to appeal to a first time database user.

Section B - 'zBASE Reference', is an alphabetical list of the zBASE commands, with the syntax for each one dealt with separately. Following that, the zBASE functions are dealt with in similar fashion.

Section C - 'Sample Programs and Glossary', contains some sample programs that can be written in the zBASE language with a brief Glossary that explains some of the terms used in the manual. Also shown is a series of zBASE programs that together form a Stock Check system,

Introduction

The Wordmongers zBASE suite is designed to provide general database management opportunities for the expanded Z88. The Z88 must have at least a 128K RAM expansion cartridge in slot 1.

...

Alternately, regularly used sets of commands may be put together into a command file to save repeated entering of the same commands. Those familiar with the dBASE family of programs from Ashton-Tate will find that there are some marked similarities between zBASE and dBASE II. (See trademark notice)

Handling, ROM's & installing the software

zBASE will only run on an expanded Z88. This means that the Z88 must have at least a 128K RAM cartridge installed. If a single RAM is fitted, it must be in slot 1.

...

To run zBASE, move the cursor to the zBASE application option in the INDEX and hit , or enter W. 

Manual conventions

See Manual conventions

Important basic concepts

zBASE is a command driven database language with over 40 commands and functions. This provides a powerful facility for programming the Z88 for data manipulation. To those familiar with dBASE II, the granddaddy database program, there should be a feeling of having seen it all before. Given that imitation is the most sincere form of flattery, these similarities are purely intentional. However, for a variety of reasons, not least of which is a 32K ROM space, not all dBASE II facilities are emulated. Equally, some have been altered in an attempt to improve and to provide a better fit with the Z88.

Certain elements of the zBASE system need to be explained early on. These elements relate to the use of variables and files.

Database areas

Data files may be opened in either of two areas. These areas are called PRIMARY and SECONDARY. These areas are labelled as 1: and 2: respectively.

The 1: and 2: symbols are referred to elsewhere in this manual as the usage area. Whenever a field variable is addressed, it must be prefixed with this usage area symbol. The single exception to this is in the use of a field's list in the LIST and DISPLAY commands.

Variables

Variables are either memory variables or field variables. A memory variable is a label for a pigeon hole containing a number or a string of letters. Such memory variables or MVARS are volatile. They exist only for as long as the zBASE program is in use. When zBASE is QUIT, memory variables are lost. When zBASE is left as a suspended application, memory variables remain preserved along with the rest of the program.

...

Field variables are treated just like memory variables except they have a 1: or 2: in front of their name to distinguish them.

Interactive versus Command file

zBASE operates in two different modes. One is called the interactive mode and the other is command file driven.

...

In command file mode, a set of zBASE commands are put together in a PipeDream plain text file. At the curly prompt, the command DO FRED will call the file called FRED and will execute the commands found in that file.

...

If it is present, the file ZBRUN will be run automatically when zBASE is started. It acts like a BOOT.CLI file.

An introduction to databases

The following sections describe the building of a database file and its interrogation. It should be read through to the end. However, computer users are notorious for skipping manual pages. In this case, all the available commands with their syntax are explained in Section B and those wishing to learn by their mistakes are invited to use that section of the manual.

In this Introduction section, an example will be used to demonstrate techniques and commands. The system is a video tape cataloguing system. It is designed to keep track of a domestic video tape library in a fashion similar to that used for books. The specific command programs used can be found in - zBASE Programs.

Files

A database file is a collection of records. Each record contains details of 1 item, e.g. a library database file would contain separate records for each book in the library. A phone book might have one record per person recorded. In a Video Library system, each record would represent a single programme or film.

...

Many database systems assign file name extensions that show what type of file it is, i.e. file.DBF shows that the file is a DATABASE File. file.NDX would be an INDEX file. This is only a convention as far as zBASE is concerned and does not need to be regarded as a rule. Having said that, some form of file name convention is useful and the sample system for Stock Control, contained in Section Cof the manual does name all command file programs with an extension of .PRG.

zBASE database files contain certain information at the top of the file that is not readable by PipeDream. Therefore zBASE data files should not be opened under PipeDream. If this does occur then the file should not, under any circumstances, be SAVED from PipeDream. It should be KILLed. If it is saved from PipeDream, the header information will be destroyed.

Records

The limit on the number of records in a database in zBASE is 65535 records.

Each record in a database consists of different fields of information.

Fields

In designing a database, much of the effort is in getting the field structure correct for the required application. The classic consideration is whether to split a name into surname and forename or to hold the whole name as a single field.

...

Although this appears elementary in the case of name fields, it is nevertheless an important consideration whatever is being stored in the file.

Data types

There are two types of data, strings and numbers. Strings are simply collections of letters and or numbers that are to be regarded as TEXT. Numbers are numeric values upon which some form of calculation may be required.

...

Similarly, a phone number is made up solely of digits but because they are not involved in calculations they are usually held as STRING fields.

Index key fields

Strictly speaking this is not a different data type. However, it is a significant consideration when designing databases so is noted here as a consideration to be included in such a design.

...

An index key field can be any string field. If the file to be indexed is expected to be large, the index field should be kept as small as possible. This then means that the index file created is as small as possible and the time taken for a rapid search is also as small as possible.

How to create a data file

Having worked out the fields required in the database, the process of creating that file under zBASE starts with PipeDream.

...

Firstly, a PipeDream document is created defining the fields and their widths. This document is saved as PLAIN TEXT.

From within zBASE itself, the CREATE command is then invoked. Each step is described in more detail below.

Defining fields, width, type

From the Z88 INDEX, use the cursor to access PipeDream by moving the cursor to the PipeDream application and pressing . A new PipeDream document will be opened.

...

The pattern to note for defining file structures is explained in more detail in Section B - zBASE Reference. In short, each line contains details of an individual field. If the field is a string field the name must end with a $, it must be followed by a comma and must end with a number defining the width of the field. A numeric field is simply described with its name and no $ and no width.

Having defined the file structure, it must be saved. Press FS, followed by a file name, say VIDEO.DEF. Move the ò 4 lines to the Save plain text prompt and enter <Y>. The key will then save this structure file in a form to be accessed by zBASE in the next stage.

Creating the file within zBASE

Returning to zBASE, the next stage occurs at the curly prompt.

...

If data is ready for input, the file should be left open. To store data to the file, the fields are treated in a fashion very similar to memory variables. The only difference is that field variables from files are preceded by a 1: or 2:. (See Section 1 above or Section B later.)

The choice of where a file is opened is managed by the SELECT command. (See INTRO part 17 and Section B of the manual.) For the moment, assuming the SELECT command has not been used, the assumed area of operation is PRIMARY, labelled 1:.

...

Further APPEND BLANK commands may be used to add more records.

Opening and closing database files

To open a database file, the command word is USE. e.g.

...

That means that the current database area is area 1. See using multiple databases for further information about database areas.

...

Apart from the USE command, the QUIT command will also close all files before going back to the Z88 applications menu.

Checking structure

A command is available to display the structure of the currently open file. The command is

}DISPLAY STRUCTURE
Database open in 1: is VIDEO
REF_NUM STRING 3
TITLE STRING 20
TYPE STRING 3
TAPE_NO STRING 3
DURATION STRING 5
RATING STRING 1
42 bytes/rec

Indexing and Index files

Most databases contain information which is entered in a random fashion. There is no pattern to the way the data are organised. zBASE uses a system known as INDEXING as a means of holding a file so that it appears to be in a specific sorted order.

This is done by the creation of a second file, used in parallel with the database itself. This parallel file, or INDEX file as it is called here, holds only a small part of the database information. Specifically it contains the data from the selected field to be used as the KEY, plus the position in the database file where the full record is to be found.

e.g. if the VIDEO file were indexed on REF_NUM$, the index file record would hold the code field, say "001", the record number "1", plus a few bytes more used for housekeeping. Since the index file is much smaller than the main database file, searches can be carried much more quickly. When the required record is found in the index, zBASE can go to the full record in the main database very quickly too.

[On a database of 580 records from a phonebook, containing name, company, phone and a 5 character key field, the typical time for a search on that keyfield is 1 second.]

In the Stock control system contained in Section C, the usual method of finding a product is by its code. Therefore, the file will be indexed on the CODE$ field.

To create the index file

some space must be freed in order to minimise the total memory used by zBASE. In this context, the space used is the database area 2.

...

The LIST and DISPLAY commands will both access the INDEX file for the order in which the display is to take place.

Using FIND

Use of the FIND command with an INDEXed file is the fastest way to search for a specific record. FINDing a record rapidly is achieved with an INDEX file as follows.

...

In command files, whenever a FIND is carried out, the next line should test for EOF()=0. If it is 0 (FALSE), then a match has been found.

Adding data to an indexed file

The fact that a file is indexed makes no difference to the adding of data except that a time allowance must be made for the updating of the index file.

...

Equally, if an INDEX file is open and an APPEND FROM command is used, the INDEX file be properly updated.

Tech note re INDEX file sizes

Given the Z88 environment, it is imperative that the amount of memory grabbed by zBASE should be kept to a minimum. This is to reflect the Z88 use of memory for all its functions and the ability to leave zBASE as a suspended application. If this is to be possible, it must use only a minimum of memory.

...

It also means that a file of say 250 records could be indexed very quickly even with a keyfield of say 20 characters.

Retrieving data

Apart from the FIND method described above, there is another way of finding particular pieces of information. This is by the use of a zBASE command called LOCATE which can search on any field. This is compared with FIND which only operates on the designated key field.

...

When used in conjunction with an indexed file, the DISP and LIST commands are very powerful. The FIND command is used to arrive at the first occurrence of the required value, then the DISP or LIST command, with its condition, can be used to show all the records which match, from that point in the file to the end.

Entering data

...

At curly prompt

APPEND BLANK

This command literally means add a blank record to the database file. It creates an empty record at the bottom of the database file in use in the currently selected area. Each field starts empty. Numeric fields start with a 0 (zero).

...

Another APPEND BLANK would immediately open another blank record ready for the next item.

Variables and Top Bit Characters

It is possible to have any name stored in a field of a zBASE record by using the decimal code of a character: For example:

...

An alternative method is to use a program called 'APPEND.PRG'. This routine emulates the dBASE APPEND command. The database to which data are to be amended must be open in area 1. TheAPPEND.PRG program must have been typed in under PipeDream and saved as PLAIN TEXT. At the } prompt, enter

}DO APPEND.PRG

...

For those who have no wish to get involved with zBASE program writing, the structure of APPEND.PRG is of no importance. It is offered as a short hand way of easily entering data to any database. See the introduction to Section C for details of how to obtain this and the other programs on a Z88 EPROM. download or on a floppy disk.

Using command (do) file

Within a command file, the APPEND BLANK command is still the only way to get a new record added to a file. However, a complete input screen may be devised using the AT SAY GET commands. This system provides the opportunity to have an input screen with proper prompts which automatically puts the data into the file without the repeated use of LET.

...

The next section is a blow by blow analysis of the input routine called, VIDINP.PRG.

* VIDINP.PRG V1.00 By Derek Fountain
CLS
SELE 1
USE VIDEO

...

The '* FLAG A' command line may be safely ignored at this stage. In the section below dealing with the use of multiple databases, this line is changed to something else to provide for additional related input.

...

With this program there is no message to the operator saying how to exit from the routine. As a first step in programming it might be a useful exercise to introduce a message saying 'Leave tape number blank to exit'. Alternatively, a different DO WHILE loop might be used to that a prompt could appear at the bottom of the program asking if there were more videos to be entered. If the response were 'N', the DO WHILE could be made to fail and so return control to the calling program or the curly prompt.

Amending data (Changing values, deleting records)

At curly prompt

Amending data is the same operation as entering data. The same LET command is used and the new data overwrites the old.

...

Tech note: The field variables from the current record are held in a temporary buffer while being manipulated. When the record pointer is moved, with a SKIP, GO, FIND, LOCATE or any other command which moves the pointer, that buffer is written back to the file. The file is not closed until a USE is issued or a QUIT. Therefore, if a fault happens when a file is open, some loss of data may occur.

Using command files

Within a command file, the GET command will be the more common method of changing variable values. If a variable contains non-blank data, that data will be displayed when the GET command is issued. That data may then be over-typed and replaced with the required new data. e.g.

...

A good example of an amending routine is SCSTOCK.PRG. It is part of the Stock Check system.

Deleting data

As with many database programs, deletion of data is done in a two part step. In the first stage, any records to be deleted are marked as such using the DELETE RECORD command. At a later time, when convenient, the file is copied across to a second file, leaving out the records marked for deletion.

...

The newly created file VIDEO will only contain those records which were not marked for deletion.

See also the PACK.PRG file.

Selection and control

One of the prime functions of a database language is not only to facilitate easy input and amending of data, but also easy retrieval of selected bits of the data.

The following commands show how such retrieval works.

At curly prompt

FIND <"field value">
FIND <memory variable>
LOCATE FOR <condition>
CONTINUE
LIST [FOR <condition>] [FIELDS <fieldname,fieldname>]
DISPLAY [FOR <condition>] [FIELDS <fieldname,fieldname>]

...

The curly prompt will not return immediately because the DISPLAY command is not intelligent enough to realise that an indexed file is in use. It continues searching the rest of the file for more hits. The --ESC- key stop the searching at any point.

LOCATE FOR .. CONTINUE

This command searches the file sequentially from the first record to the bottom of the file.

...

Having found a hit, the CONTINUE command will continue the search on the same basis. The search will continue from the current record to the bottom of the file.

LIST [FOR <condition>] [FIELDS <fieldname,fieldname>]
DISPLAY [FOR <condition>] [FIELDS <fieldname,fieldname>]

These two commands are very similar except that the DISPLAY command will only display records 7 at a time whereas the LIST command will scroll through all the hits without stopping.

...

}LIST FOR 1:TYPE$="COM" FIELDS TYPE$,TITLE$,TAPE_NO$

In command files

The DISPLAY, LIST and ? may be used within a command file in order to provide structured output to the screen. The operator may be prompted to input the piece of data to be matched and the command file could then display that data in a structured fashion.

...

AT line, 2 say 1:REF_NUM$
AT line,10 say 1:TITLE$
AT line,32 say 1:TYPE$
AT line,37 say 1:TAPE_NO$
AT line,42 say 1:DURATION$
LET line=line+1
CONTINUE
ENDDO
AT line,1 say "End of file found."
RETURN

See also SCSIFIND.PRG.

Manipulating data files

Data is collected for a variety of reasons. Sometimes its like an antique collection with bits of information collected so long ago that there is no relevance to that data. However, assuming the data is to be used, it must be available in different forms. This is especially true on the Z88 when it will often be used as a temporary home for data to be transferred to another micro.

...

PipeDream format, with the PD option at the end of the line, would create a file with each record on a line with  characters between fields. To load the file in PipeDream it must be loaded as Plain Text. Any fields of width greater than 12 will appear to be condensed. They are still there but the individual column widths will have to be reset to the required width in order to get all the data to appear.

...

Delimited means that the file is created for access by PipeDream with each record separated by a carriage return and each field is separated by a comma (,). This format is of particular interest to those wishing to export data to other database systems outside the Z88. Programs like dBASE II, III, IV and WordStar can use comma delimited files as raw data.

COPY TO filename [PD] [FOR <cond>][DELIMITED] [FOR <cond>]

COPY TO <filename> This version creates a straight copy of the file in zBASE format. e.g.

...

The whole file is copied to a PipeDream column format to be loaded as Plain text and the column widths adjusted as explained in the introduction to this section.

...

The resulting VIDCOM file, when loaded as PLAIN TEXT under PipeDream, would look like this:

...

If the file to be copied to has been created previously, the COPY TO command will overwrite it WITHOUT WARNING.

APPEND FROM filename [PD] [DELIMITED] [FOR <cond>]

The file in use must be open in the PRIMARY database area and the SECONDARY area must be empty i.e. it must be CLOSED. (See DISPLAY STAT for how to check whether an area is in use.) The file from which data are to be appended must not be open.

...

The PD qualifier means that if a PipeDream columnated file has been saved as Plain text, each line will be treated as a database record and read into the file.

...

The FOR <cond> option is only available when appending from another zBASE file. In this case each record in the source file is checked against the condition. If the condition evaluates to TRUE, or to a NON-ZERO value, the record will be added to the open target file.

COPY TO filename <[STRUCTURE] / [PD]>

This form of the copy command provides the opportunity to re-create the structure of the current file in another database file, or as a skeleton in PipeDream for the creation of a new file.

...

n P and into PipeDream

Load TEMP as plain text. Go to the bottom of the file and add a line

...

The new file VIDEO now contains all the records from the previous VIDEO file with an additional field called COST of type NUMERIC.

COPY TO <filename> STRUCTURE

This version of the command will create a new database file with the same structure as the current file. The new file will have no records.

Moving around a file

These commands position the record pointer to the selected record. If the record number is known, the 'GO record number' command is the fastest method of reaching a record.

SKIP

The SKIP command moves the record pointer in the direction given in the command. SKIP 3 will move the pointer on three records. SKIP -3 will move the pointer back three records.

If the end of file is reached, the EOF() function will return a non-zero value, i.e. TRUE, and the record number, RECNO() will return a 0. SKIPping past the end of file will return RECNO()=0 and EOF()=1.

GO (TO RECORD NUMBER ..) <expression>

The GO number command places the record pointer at that record number. The number must be a numeric variable or numeric expression, except when it is BOTTOM or TOP.

GO TOP, GO BOTTOM

These commands position the pointer to the respective position at the top or bottom of the file. The record to which it is pointed is a live record and is not in front of the beginning of the file nor is it after the end. i.e. GO BOTTOM will go to the last record not to the end of file so EOF() will return FALSE.

ENVIRONMENTAL COMMANDS

-ESC- ON/OFF (v1.3 only)

The switch allows programs to ignore attempts to -ESC- and is activated by typing Set Esc=Off (deactivated by Set Esc=On) in interactive mode or by inserting it to a command line.

SET ECHO

This is a toggle command in that the first call will switch it on and the second will switch it off.

It is a programmers tool to show what command line is being executed. It is most use when debugging command files. It makes a mess of the screen but displays each command line as it is executed.

Indirect variables

&memvar

In dBASE II, these are referred to as MACROS. These & characters mean that the variable which follows the & is evaluated before being executed. In any command line from the keyboard or a command file, in which an indirect variable is found, the &variable is first replaced by the value it represents. e.g.

...

In any real program, the above would be written as GO BETA and the above is given as an example only. For a more extensive example of the use of indirect variables, see the APPEND.PRG program.

"&numericvar"

This is a particular use of the indirect variable and converts a numeric to a string.

LET numvar=42
? "&numvar"
42
? len("&numvar")
2

zBASE output to printer port

The command for this is
# "text"
or

...

See section C for a program for printing address labels.

Z88 output facilities

The copy commands explained above provide an opportunity to output to PipeDream. The method described below permits all the screen output to also go to a file or the printer.

n+ P

This sequence echoes all screen output to an attached printer. Keyboard input is double spaced at the printer.

n- P turns off this echo.

n+ S

In a similar fashion to the above printer echo system, this sequence echoes the screen output to a file. The file may be accessed via PipeDream by loading the file ram.-/s.sgn.

The switch to turn off the file echo is n - S.

• The maximum command line length is 255.
• The maximum string variable length is 255. (Memory or field).
• Maximum number of fields per record is 32.
• Max number of nesting of IF/ENDIF loops is 255.
• Max number of nested DO WHILE's is 32
• Max number of nested DO files is 16
• Max area for memory variables is 512 bytes
• Max length of variable name is 8 characters
• Numbers are significant to 9 digits.
• Max number of decimal places is 8.

Precedence of Operators

zBASE does not consider one type of operator any more important than another. All mathematical expressions are evaluated from left to right. The only exception to this rule is that the contents of brackets are evaluated first. Programmers will quickly notice that expressions with brackets are evaluated relatively slowly, and that sorting out the expression will make the program run faster.

Using multiple files

Using multiple databases.

There are many instances in data manipulation when data from two or more databases has to be combined to achieve the desired output. zBASE supports this requirement by allowing two databases, with indices, to be open at the same time. They can then cross reference each other and find the required information without opening and closing the files.

...

There will be one record in the VIDSTAR file for each star in the film. So if the film has three stars, the VIDSTAR file will have three records, where the REF_NUM is the same as the REF_NUM of the films record in the VIDEO file, and the STAR field holds the name of one of the three stars. An example will help: 

The data for the VIDSTAR file must be entered when the other details of the video are being entered. To alter the program VIDINP.PRG to do this, find the line in the program:

...

The simple subroutine below, STARINP.PRG, should then be entered using PipeDream and saved as plain text.

* STARINP.PRG V1.00 By Derek Fountain
CLS
USE VIDSTAR INDEX VIDSTAR.NDX
AT 0,28 SAY "Home video library system"
LET header$="Enter the stars who appear in "+TRIM(mtitle$)
AT 2,(80-LEN(header$))/2 SAY header$
AT 6,25 SAY "Leave the field blank to exit"

...

If the entry is not blank a new record is created in VIDSTAR. That record is filled with the unique reference number of the video, as created by VIDINP.PRG, and the stars name, as input by the user.

...

Each record of this database will contain one line of the report, which will be loading into, and printed from, PipeDream. This means three databases have to be manipulated: 

...

The REP file is open from start to finish in area 1, and the other two are opened and closed as necessary in area 2.

...

Copy out the file to a PipeDream file, close the database, and wait for acknowledgement that the process has finished. Then delete the work file and return.

Importing files from PipeDream

When data has been entered previously under PipeDream, it can be imported directly into zBASE using the APPEND FROM command. Assuming the PipeDream data are arranged in columns, separated by TAB characters, each line of data can be read in as a record. Each column is then a field.

The phone book from the Quick Start Guide might look like this in PipeDream. It is called PH.DAT and is stored as PLAIN TEXT.

...

The QSG section has a structure of

...

Fields which are too big for the database field sizes specified will be trimmed to size by lopping off the last characters.

Editing command files

Editing command files and instantly testing them is extremely simple. It can be done by using nP to go into PipeDream, and nW to return to zBASE.

Popdowns from zBASE.

Z88 popdowns may be used while in zBASE. However, the 
following points should be noted.

CONVENTIONS

...

Lowercase	operator input, usually enclosed in < > brackets.
UPPERCASE	specific zBASE commands or command words.
[....]	Optional parts of commands.
<...>	Operator specified input.
<exp>...	An expression which can result in either a number or a string. e.g. 5+5, "FRED"+"BLOGGS", a$+"MUMMY".
<var> ...	A variable, can mean either mvar or fvar.
<mvar>...	A memory variable, not stored in a database, but in a large buffer in RAM. An mvar is defined as a string if its name ends with a '$', otherwise, it is defined as a number.
<fvar>...	A field variable, permanently stored in a database. Fields must start with either a 1: or 2: label, depending on the database they are to be taken from. If the label is missing the field will be taken as a mvar.
<cond>...	A condition which returns the result either TRUE or FALSE. e.g. 10=10 is TRUE, 10=6 is FALSE, "FRED"="BLOGGS" is FALSE. A single number 0 is evaluated as FALSE, any other number is TRUE.

...

zBASE Commands

Most of the zBASE commands may be used both in the interactive mode at the curly prompt, or in program files or command files. The main exceptions to this rule are that related pairs of commands such as IF/ENDIF and DO WHILE/ENDDO may not be used in the interactive mode.

...

At present only a single condition is allowed. i.e. there are no AND, OR or NOT clauses.

KEYWORDS

Only the first 4 characters of a keyword are significant.

* Comments

Any line beginning with an * will be ignored. This can be used as a method of putting comments in command files. e.g.

}* This is a comment line and will be ignored
}

? [<exp>]

This command shows the value of an expression. The result is printed at the current cursor position, with no CR or LF following.

...

}? "Hello world"
Hello world
}? 10+10
20
}? 1:phone$
01296 43 78 78

# [<exp>]

This command works just like the ? command, only the expression is sent out of the serial port, instead of to the screen.

AT <co-ordinates> SAY <exp>

This command prints the value of the expression at the specified co-ordinates. The co-ordinates are taken as 'down' (0-7) then 'across' (0-79). A string will be printed in full, including trailing spaces and a number will be printed to 9 significant digits and up to 8 decimal places. e.g.

}AT 3,40 SAY "Merry Christmas"


Merry Christmas

AT <co-ordinates> GET <var>

This command allows the input of a variable, either field or memory variable. The co-ordinates are taken as for AT SAY with the variable then being offered up at the specified co-ordinates for editing. The variable must exist prior to the issuing of the GET command.

...

LET mvar$="0101 212 800 5555"
AT 3,30 GET mvar$

APPEND [BLANK] / [FROM <filename> [PD]/[DELIMITED] [FOR <exp>] ]>

This command is used to add new records to the currently selected database.

...

The PD clause means the fields are separated by TAB (09h) characters and the records are separated by CR (0Dh) characters.

The command line is

APPEND FROM [filename] PD

The file shown below, having been saved as PLAIN TEXT, will then be appended onto the end of the database.

...

The DELIMITED clause means the fields are separated by commas and the records by CR (0Dh) LF (0Ah). This is a common format output by dBase and many spreadsheets.

...

The following file would be appended to the database in use.

...

...

If the PD and DELIMITED instructions are omitted the file is assumed to be a zBASE file.

CLS

This command clears the screen.

CONTINUE

This command locates the next record which matches the condition specified in the last LOCATE command.

...

The CONTINUE command is not designed for use with the FIND command. If CONTINUE is used after a FIND it is only coincidence if matching records are found.

COPY TO <filename> [PD] [DELIMITED] [FOR <cond>]

The copy command is the method of outputting data to another format. If none of the options are specified the output file will be another zBASE file.

If PD is specified the data will be written out in a format which PipeDream can read in plain text mode.

e.g. COPY TO <filename> PD

If DELIMITED is specified the data will be written out in a comma delimited format which can be read in by dBase or a Spreadsheet package. e.g.

COPY TO <filename> DELIMITED

If the FOR clause is specified only those records which meet <cond> will be copied to the output file. e.g.

...

copies the same set of records but this time the output is in PipeDream format. Similarly, the use of DELIMITED would out to a comma delimited file.

COPY TO <filename> [STRUCTURE] [DELIMITED]

This second version of the COPY command provides two alternative outputs.

...

COPY TO <filename> STRUCTURE DELI, creates a PipeDream file of the form required to create a new zBASE file. The new file created from such a file would have the same structure as the original database from which the structure was taken.

CREATE <file1> FROM <file2>

This version of the CREATE command creates a database file called 'file1' from an input file, 'file2' which is created under PipeDream. The format for file2 must follow these rules:

1. One line per field in database.
2. No blank lines, and no extra CR at the end of the last field.
3. All string field names end in $, followed by a comma and a number indicating the length of the field (1-255).
4. Numeric fields have just the name on the line, nothing else.

e.g. 

Any stray CRs, or text in the wrong place may cause strange results.

The database file created will be left open in the selected database area. If the CREATE fails for any reason, the selected area is left empty.

DELETE <[RECORD] / [FILE <filename>] >

The DELETE RECORD command marks the current record for deletion. The record is not actually removed from the file. When the record is DISPLAYed a '*' will appear next to the first field indicating the record is marked for deletion.

To actually remove deleted records from the database, see the program PACK.PRG.

DELETE FILE filename will erase the file from the Z88's Ramdisk. If it doesn't exist, an error message will appear.

DISPLAY/LIST <[STRUCTURE]/[MEMORY]/[STATUS]>/ 
<[ALL]/[FOR <cond>]> <[FIELDS field list]>

The display commands can be called using the LIST keyword. The only difference in their operation is that DISPLAY pauses for each screenfull of data, and LIST doesn't.

...

If the MEMORY clause if used, the memory variables and their values are listed on screen. e.g.

If the STATUS clause is used the machines current status is displayed on screen.

...

Note that the 1: is not required for the list of field names.

DO <command file>

This command executes the specified command file. All commands in the file are in standard zBASE syntax. Control is passed back to the keyboard when the last instruction has been executed, or a RETURN is encountered.

DO WHILE <cond> - ENDDO

The DO WHILE command can only be executed from within a command file. The condition is evaluated, and, if it is TRUE the statements following the DO are executed until an ENDDO is found. At that point control is passed back up to the DO and the condition is re-evaluated.

...

Also note the expression 'DO WHILE 1' would put the machine into an infinite loop.

FIND <exp>

Find searches the current index file for the value <exp>. It is zBASE's quickest method of finding data, searching some 4000 bytes per second. The only field it scans is the index key field. e.g.

}USE TEST
}INDEX ON NAME$ TO TESTNAME.NDX
}FIND "Derek Fountain"
}DISPLAY
465 Derek Fountain Aylesbury
}FIND "Aylesbury"
}DISPLAY
0
}INDEX ON TOWN$ TO TEST.NDX
}FIND "Aylesbury"
}DISPLAY
465 Derek Fountain Aylesbury

GO [<exp>/<BOTTOM>/<TOP>]

The GO command positions the current record pointer at an absolute record number, specified by exp. Trying to move to a number less than 1 will place the record pointer at 1, and trying to move to a record number which doesn't exist will place the record pointer at the last record in the file (not EOF).

...

} ? RECNO()
24
} GO 10
} ? RECNO()
10
} LET a=30
} GO a
} ? RECNO()
30
} GO BOTTOM
} ? RECNO()
98
} GO TOP
} ? RECNO()
1

IF <cond> - ELSE - ENDIF

The IF command allows conditional execution of statements from within a command file, but without the looping system the DO WHILE statement uses.

...

In the second example, if a$ is the same as b$ then 'Its equal' will be printed, followed by 'Goodbye'. If a$ is not the same as b$, then 'Its not equal' will be printed, followed by 'Goodbye'.

INDEX ON <fvar> TO <filename>

Index is zBASEs method of sorting a database, and keeping it sorted. When a database is indexed on a field, any records that are appended to it automatically take up their correct place in the file. If the file is USEd without the index file, the records go back to chronological order. E.g.

}USE TEST
}LIST ALL
1 Fred
2 Bob
3 Peter
}INDEX ON NAME$ TO TEST.NDX
}GO TOP
}LIST ALL
1 Bob
2 Fred
3 Peter
}APPEND BLANK
}LET 1:NAME$="Derek"
}GO TOP
}LIST ALL
1 Bob
2 Derek
3 Fred
4 Peter
}USE TEST
}LIST ALL
1 Fred
2 Bob
3 Peter
4 Derek

LET <var>=<exp>

The LET command assigns a value to a specified variable. In the generic case, the value to be allocated to the variable is the value of the expression <exp>. The label to be given to the variable is the name contained in the space <var>. e.g.

LET today$=date()
LET spaces$=" "
LET codename$="Fred"

LOCATE FOR <cond>

The locate command is used for finding a record which meets a specified condition. The record pointer will be moved to the top of the file and each record checked to see if <cond> is true. If it isn't the next record is checked and so on until the EOF is found or a record meets the condition. The record pointer will be left pointing to the correct record, or EOF if there wasn't one. e.g.

} ? RECNO()
24
} LOCATE FOR 1:NAME$="Fred"
} ? RECNO()
14
} LOCATE FOR 1:NAME$="Gertrude"
} ? EOF()
1

QUIT

This command closes all open files, and returns the Z88 back to its main applications menu.

RECALL RECORD

This command performs the opposite of the delete command. A record marked for deletion will be 'unmarked'. If the record wasn't deleted, the command is ignored.

RELEASE <mvar>

When a memory variable has served its purpose and is no longer needed, it can be removed from RAM to free space. e.g.

} RELEASE name$
} ? name$
Variable not found

RENAME <file1> TO <file2>

This command renames file1 to file2 in the same way the option from the Filer does. If file2 exists or file1 doesn't an error message will appear. Note you can't rename a file which is open.

RETURN

Return halts the execution of the current command file and returns control back to the curly prompt or the calling file.

All files are left open and memory variables are maintained.

SELECT <[1 or 2]>

zBASE can have two databases open at the same time, for cross referencing purposes. This command selects between the two database areas and defines which database will be used for DISPLAY commands, and which area a new database will be opened in when a USE command is issued.

The two areas are called PRIMARY and SECONDARY or simply 1 and 2. Only the 1 or 2 may be used in the actual command.

SKIP [<exp>]

The skip command moves the current record pointer. If <exp> is specified it must be a number. The record pointer will move that number of records through the file, from its current position. A negative number will make it move backwards. Trying to move past the beginning of the file will leave the record pointer at record 1, and trying to move past the end of the file will set EOF true.

...

} ? RECNO()
24
} SKIP
} ? RECNO()
25
} SKIP 10
} ? RECNO()
35
} SKIP -4
} ? RECNO()
31

USE [<file>]

This command opens a new database in the currently selected area. If the filename is not specified the database currently open is closed and the area left empty. Only files created with the CREATE command can be opened using USE. i.e. only zBASE files.

The alternative form opens an associated INDEX file viz:

USE file INDEX file

WAIT

This command simply pauses the system until a key is pressed. When used in a command file it is useful to display a 'WAITING' message so that the operator knows that a key is awaited.

If this is done, the 'WAITING' message should be erased after a key press.

zBASE Functions

zBASE supports all the standard functions found in other languages plus some specialised database handling ones of its own.

...

} LET A=2.03
} LET A$="&A"
} ? "-"+a$+"-"
-2.03-

CHR(<exp>)

The CHR function returns a single character string containing the character whose ASCII code is <exp>. e.g.

} ? CHR(65)
A
} ? CHR(124)
|

CLI (<exp$)

The CLI function sends <exp$> to the OZ CLI function for immediate execution.

DATE()

The date function returns the current date as an eight bit string. The date is taken from OZ, and is returned in the system default format i.e. European or American as set by the panel. e.g.

} ? DATE()

18/08/88

DELETED()

The DELETED function returns a 1 (TRUE) or a 0 (FALSE) depending on whether the current record is marked for deletion or not. e.g.

} DELETE RECORD
} ? DELETED() 1
} RECALL RECORD
} ? DELETED()
0

EOF()

The EOF (End of file) function returns a 1 (TRUE) or a 0 (FALSE) depending on whether the current file record pointer is at end of file or not. e.g.

} GO BOTTOM
} ? EOF()
0
} SKIP
} ? EOF()
1

FILE(<exp$>)

The FILE function returns a 1 (TRUE) or a 0 (FALSE) depending on whether the file <exp$> exists or not. Note that <exp$> is an expression and not a literal. e.g.

} ? FILE("NAMES.DBF")
1
} USE NAMES.DBF

INT(<exp>)

The INT (Integer) function removes all digits from the number <exp> which follow the decimal point. e.g.

} ? INT(3.142)
3
} ? INT(200.000)
200
} ? INT(22/7)
3

LEN(<exp$>)

The LEN function returns the length of string expression <exp>. e.g.

} ? LEN("HELLO WORLD")
11
} LET A$="FOO BAR ZOK POW"
} ? LEN(A$)
15

LOWER(<exp$>)

The LOWER function turns all the characters in the string <exp> into lower case. Any characters that were already in lower case will be left alone. e.g.

} ? LOWER("Fred Bloggs")
fred bloggs

LTRIM(<exp$>)

The LTRIM function removes all leading spaces from the string expression <exp>. e.g.

} ? "1"+LTRIM(" 2345")+"6"
123456

RAM()

reveals RAM space available on currently selected device.

RECNO()

The RECNO function returns the current file current record number. e.g.

} GO 10
} ? RECNO()
10
} GO BOTTOM
} ? RECNO()
98
} SKIP
} ? RECNO()
0

SET ECHO

toggles echoing of all commands to screen.

STR

To emulate a STR function use &.
} LET A=2.03
} LET A$="&A"
} ? "-"+a$+"-"
-2.03-

SUBSTR(<exp1$>,<exp2>,<exp3>)

The SUBSTR (Substring) function returns that part of <exp1$> that starts at <exp2> and is <exp3> characters long. Examples make this clearer:

...

Note that if <exp2>+<exp3> > LEN(<exp1$>) no error occurs.

TIME()

The time function returns an eight character string holding the current time in the format HH:MM:SS. The time is fetched from OZ and can be altered using nT. e.g.

...

To obtain time differences, sub strings of the time string will have to be extracted and converted to numbers using the VAL() function.

TRIM(<exp$>)

The TRIM function removes the trailing spaces from the end of string <exp>. e.g.

} ? "1"+TRIM("2345 ")+"6"
123456

UPPER(<exp$>)

The UPPER function turns all the characters in the string <exp> into upper case. Any characters that were already in upper case will be left alone. e.g.

} ? UPPER("Fred Bloggs")
FRED BLOGGS

VAL(<exp$>)

The VAL function turns an ASCII string into its numeric equivalent. Conversion stops at the first non ASCII digit character. e.g.

} ? VAL("123")
123
} ? VAL("10")+10
20

WHERE(<exp1$>,<exp2$>)

The where function returns the position of <exp1$> in <exp2$>. If it is not present, 0 is returned. e.g.

} ? WHERE("23","1234")
2
} ? WHERE("HELLO",UPPER("hello world"))
1
} ? WHERE("78","1234")
0

Wordmongers Stock Control System

This suite was written to demonstrate zBASE' ability to run fully menu driven suites. It was designed with a small shop in mind, where the manager would go round his warehouse, with his Z88 and take a check of all the items he has in stock. The system would then produce a report giving details of how many of product X was in stock and how much it was all worth.

...

Option 4 produces a Pipedream plain text file, including all details held in the products file.

...

Option 5 produces a Pipedream plain text file, including all details held in the suppliers file.

...

Here is a list of the files required to run the system. The files can be obtained by sending a blank 32k eprom to us or downloading the zip file.
