TAB	is like the tabulate key on a typewriter. Use it for making columns of figures, or arranging tables.

INDEX	will return you to the Index from within an application.
HELP	gives you a display of information about the action you are currently carrying out. Further information is then available on related topics.

This example shows how you can enter any type of information such as a library catalogue, a book index or bibliography, or a name and address list into the Cambridge Z88 using PipeDream.

When you start a new sheet in PipeDream you are given six columns, each 12 characters wide. Although you can enter lines of text much wider than this in each column, it will make working with the name and address information simpler if, at this point, you make each of the columns in the document wider. You do this with the Width command in the LAYOUT menu.

Enter the other names and addresses given below on lines 3, 4, 5, and 6 of your document in exactly the same way. Of course, if you prefer, you can compile your own list. If part of an address is too long to fit within one column, just keep typing; although you will not be able to see all the information in that column, it will be retained and you will be able to refer to it later.

Saving the document

Since by now you may have spent some time entering information into your document, it is a good idea to save a copy to the Cambridge Z88 filing system in case you accidentally lose the information during the next experiments. You save a copy of the document by using the same procedure as the one used for the party invitation.

Select the Save command by pressing the 

Type addresses as the name of file to save, ignoring the other options since you want to save the whole document, and press 

Sorting the information

Now that you have entered a table of names and addresses, it would be useful to have them sorted into alphabetical order so that you can look up a particular name more easily.

First you need to specify which part of your document you want to sort. Move the cursor to slot A2, the top left-hand comer of the table of names and addresses, using theand keys keys to move up and down the document and the 

...

Now mark the bottom right-hand corner of the table of names and addresses. Move the cursor down to row 6 and across to column F with the   key and thethe 

...

Move back to the left-hand side of the sheet with

We wish to sort the names and addresses into alphabetical order of the names, which are in column A, so type A to the prompt

and press the 

...

You could, of course, have sorted the information on a different heading by specifying another column, rather than column A, when you gave the Sort command. For example, you may like to experiment with sorting the same names and addresses on the Town column, or on the column containing the peoples' ages.

Finding information

You could have entered many more names and addresses than the few you have already stored without running out of space in the document.

You can see how much space is available in a document at any time by typing O to display the Options Page. The number of characters of space available is given after the heading Free on the right-hand side of the Options Page display. Press ESC Press 

In a large list of names and addresses, it would be very inconvenient to have to search around in the list for a particular name or address. Fortunately, there is a much faster way, using the automatic search facility built into PipeDream.

Select the Search command from the BLOCKS menu in the usual way: display the BLOCKS menu with thethe 

The Search command displays a number of options which allow you to specify exactly what you want to search for, and whether you want to restrict the search to a particular part of your table of information. For example, you might want to search for the address of someone whose surname you had forgotten, but whose Christian name you knew to be Max. You would then enter Max against the first option:

...

Search only range of columns    Yes A

Then press 

Incidentally, if the name you chose to search for found someone else with the same name first, you could use the Next Match command on the BLOCKS Menu to move on and find the next item that contained the same name.

Help with searching

It is a peculiarity of the way we remember information that we can often only remember part of what we are trying to recall. For example, we may know that the person we are trying to find lives in a town called something like Caxton - or perhaps it was Croxton? Or then again, perhaps it was Foxton. The PipeDream Search command has two facilities which help in just this type of situation.

...

and you would be sure to find it.

Printing information

To print out the information in your name and address list as an orderly table, select the Print option from the PRINT menu. Press the 

Since the total width of the table of names and addresses is 144 characters (six columns of 24 characters) it will probably be too wide to fit across the width of the paper on your printer; most printers will only print 80 characters. You will therefore need to print the table in two sections, by selecting a range of columns in each case.

...

Print only range of columns Yes A C

Then press the 

...

Alternatively, some printers will print up to 132 characters across; in this case you may be able to fit the whole table onto a single sheet of paper by first reducing the width of some of the columns using the Width command on the LAYOUT menu.

Printing selected rows

If you were going to use the name and address list for a business mail shot, you might want to compile a selective list containing only the names and addresses of people living in one particular area. The PipeDream Print command caters for this by allowing you to specify a test to be performed on each row of the document. Only those rows for which the test succeeds will be printed.

...

For example, to print out the names and addresses of all the people living in Hants or Surrey, give the Print command in the usual way by displaying the PRINT menu and then pressing pressing
