100 The Built-in Software
prepares the disk for use by dividing it into sectors compatible with your disk
drive and by establishing a disk directory.
There are two ways to format the disk:
1. You can format the disk iron BASIC by using the HEADER cornmaad. Use
HEADER if you have not yet turned on the built-in software and you know
you will want to store your work on a disk. The HEADER command is
explained in Chapter 1.
2. You can format the disk from within the built-in software by using the
FORMAT command. The FORMAT command can be issued only from the
spreadsheet program. The FORMAT command is explained in Section 3 of
this chapter.
Now: Do not store file manager files on a disk that contains any other type of
file, including word processor or spreadsheet files. Each file manager file should
have its own disk.
Drawing Bar Graphs
The built-in graph generator is actually a part of the spreadsheet. The graph
generator has no commands of its own. You create the graphs by entering
numbers in the spreadsheet, and you can transfer the graphs to the word proces
sor to print them as part of a document.
To create bar graphs, follow these steps:
1. If you want to keep a copy of work in either work area, use the SF (Save File)
command to store the work on a disk. Clear the word processor and spread
sheet work areas with the CM (Clear Memory) command.
2. Switch to the spreadsheet (Q C, then TC and RETURN).
3. Type the numbers for the graph in the first row of the spreadsheet work area.
Be sure to type numbers only in the top row.
4. Issue a MAP command to tell the computer you want to send the graph to the
word processor.
5. Switch to the graph generator (g C, then GR and RETURN). The graph is
automatically drawn using the numbers you entered in the spreadsheet work
area.
6. Press RETURN to return to the spreadsheet.
7. Switch to the word processor (g C, then TW and RETURN). The graph is
displayed at the top of the word processor work area. When the graph is in the
word processor, you can make any needed changes to the graph.
