Introduction

This space provides details about how you can use PC PipeDream as a companion to your Cambridge Z88 portable computer, on any desktop that can support MS DOS virtualisation. It does not go into detail on all the commands, or to replace the manual (which is still available). The aim is

• to give a bit of history about the product
• a brief description
• to show the similarities and differences between the PC and Z88's versions
• show how the files can be converted to different formats so that they can be used with modern programs
• check whether files can be transferred from and to the Z88 with the different virtual machines.

History

PipeDream was an evolutionary product. It is a word processor, spreadsheet and database rolled into a single program.  Its origins lie in View, Acorn's word processor for the BBC micro and Master series. Written by Mark Colton, PipeDream as a concept first appeared as View Professional for the BBC micro for the British educational market. Subsequently it was adopted and bundled in with the Cambridge Computer Z88. In 1988 PipeDream, two versions were released with additional spreadsheet functionality. One for the Acorn Archimedes, and the other for the IBM PC and compatibles (using 16-bit MS DOS),. There was an optional spellchecker, but this now is included in the current version. It is the PC version that we are using in this article.

Looking back at my (Vic Gerhardi, Rakewell.com, ed.) records, the first contact I had with Colton Software was on the recommendation of Tim Routsis on the 28th January 1988. Subsequently on the 18th May, I ordered

The Z88 was already in the marketplace and there was a growing demand for PipeDream to be available on the PC. There was a saying then that 'Nobody got the sack for ordering a IBM PC,' so there was a bit of a race on to see which of the many software products would become a 'market leader.'

PC PipeDream is still a useful tool to work on your transferred PipeDream documents, post-processed on your modern power-desktop such as Windows XP and newer, MAC OS X and Linux systems. How is that possible, when PC PipeDream is a DOS application? The answer is through virtualisation. The screenshot below comes from a running PC PipeDream on a 64-bit Windows 8 Desktop.

Description

On loading, PipeDream presents a spreadsheet layout of just one row. As rows are added the rows and columns create a matrix of hidden cells. It can be used just for that purpose, as a spreadsheet. If a word processor, is required just start typing. The spreadsheet layout is just as amenable to word processing as to spreadsheet use. If an embedded spreadsheet is entered in the text,  use the spreadsheet functions in the cells. Referring to the text and values elsewhere in a spreadsheet  is just as straightforward. Text and numeric data may easily be treated as records within a database for retrieval as required.

Think of PipeDream as a sheet on which text, spreadsheets and databases may all be set up. A menu bar at the top of the screen gives access to seven pull-down menus. These may be accessed by pressing the 

WORKING WITH TEXT

The first step in using PipeDream is learning how to move about the sheet, up, down left and right. Text may be entered starting in any column and will extend to the right till the right-hand margin for that column is reached. Multiple column format is easily achieved with separate right-hand margins for each column. All the expected word processing operations are catered for and work well. Blocks of text are highlighted by moving to the start and the end, and may then be moved, copied or deleted. Text can also be surrounded by special markers to indicate the use of bold, italics etc on printing. Tab stops cannot be set and used in the accepted way, as the 

WORKING WITH NUMBERS

Numbers and expressions, including a wide range of special functions, may be entered into any slot if first designated as an expression slot (this can also be set up as a default). Expressions may consist of numbers, dates, functions, conditions, strings, ranges, lists and slot references (a range is a consecutive set of cells, a list of individual cells). These may be entered individually or combined using various mathematical and conditional operators. Fourteen mathematical functions are provided, plus 11 financial functions (e.g. loan repayment, cash flow etc.), 13 general functions and 9 database functions.References can be entered into expressions by moving the cursor to the appropriate cell, but this is not as automatic and requires an extra key depression ( 

DATABASE FUNCTIONS

Any data may be inserted in rows and columns to form a database. Values may be sorted or matched, and some nine special functions will perform tasks such as totaling and locating maximum and minimum values. The facilities are a long way short of any full blown database system, but useful none the less in the context.

OTHER FEATURES

The menu system works well and provides a wealth of functions. Page layouts are readily created with headers and footers as required with good control over printing including various highlights such as italic and underlined text. Printer drivers are supplied for the Juki 6100 and Epson FX80, but other drivers are readily created by editing the files supplied using PipeDream itself.There are also facilities to enable files to be transferred between PipeDream and Lotus 1-2-3, and of course there is complete compatibility between the Archimedes version of PipeDream and those running on the PC or Z88.

CONCLUSIONS

PipeDream has much to commend it, not least an excellent manual. There may be word processors or spreadsheets which offer more in their respective applications, but for its unique combination of talents PipeDream has much going for it.

Screen Size

There are two sizes of the screen, the 'Deep Screen' mode size is shown above, whist the normal display is shown below.

Menu, Mouse and Cursor Operations

There is no mouse support. All operations are given by using

• keyboard commands or
• by using the Menu commands which are shown along the top horizontal banner. Using  

Z88 Users will notice that the command letters match the ones they are used to (with a few exceptions). The 

 key on the PC replaces the  Key.

Selection of the commands, once in the menus, can also be selected using the , ,  and  cursor keys.

Using Virtual Machines

There are a number of gotchas, when using two computers.

• File names - Remember which computer the files are in. In the following example, the files are on the Virtual Machine, not the Server. They both have C: drives and it is easy to get them muddled up when working with the same keyboard, mouse and display.

DOS and Windows File names

A DOS file name is in the format of eight characters, a period (.) then a further 3 characters. This is described as 8.3 file name. A windows file name can, and usually is, longer. The effect of this is that when a Windows file name is viewed in a DOS program, the file name does not appear correctly. See what happens when using the following command.  

Notice that the DOS directory is shown as C:\PROGRA~1\DOS\PIPED whilst in Windows it is C:\Program Files\DOS\PIPED. 

Saving files

When saving files, 

The only line that we are interested in is the last one. There are five options.

Converting Files

IBM have taken over from Lotus with the Smartsuite product and it is still available.  Fortunately, I still have that product. The oldest one that has AmiPro 3.1 for Windows 3 installed on the Virtual Windows xp Professional using the same procedure below.

This program supports the following conversions

Database

• dBase/ANSI (*.DBF), dBase/ASCII (*.DBF)

Spreadsheet

• Lotus 1-2-3 (*.W*), Lotus 1-2-3  97 (*123),Lotus 1-2-3 for OS/2 (*.WG*),Lotus 1-2-3 R3 (*.WK3),Lotus 1-2-3 R4 (*.WK4),
• MS Excel (*.XLS), MS Excel 3.0 (*.XLS), MS Excel 4.0 (*.XLS), MS Excel 5.0 (*.XLS), MS Excel 7.0 (*.XLS), MS Excel 97 (*.XLS), 

Word Processing

• MS Word Word 97 (*.DOC), MS Word Word for DOS 3, 4, 5, 6 (*.DOC), MS Word Word for OS/2 (*.DOC), MS Word Word for Windows 1.0 (*.DOC), MS Word Word for Windows 2.0 (*.DOC), MS Word Word for Windows 6.0 (*.DOC), MS Word Word for Windows95 7.0 (*.DOC).

A full listing of all the conversions are listed here.

The problem of finding file converters, has now been removed..

Design a test spreadsheet

It was decided to have a look on the web to see if there was a spreadsheet that could be used as a test. It was decided to use a paper that had been written about the issues and then use the examples there to convert between the two programs.
