Notes and Suggestions
If you run out of disk space, ThinkTank will display the
message DISK FULL! See the error messages section for sug-
gested courses of action.
You can avoid these conditions by using the PERCENT com-
mand to monitor your use of internal memory and disk space.
You give this command by pressing the percent C”%”) key at the
Top Level of ThinkTank. ThinkTank responds by displaying the
percentages of memory and disk space still available. If you
are running short, you can take corrective action before it’s
absolutely necessary.
changing ThinkTank’s Command Keys
When you press a key to give a ThinkTank command, it
seems to trigger the command directly. Actually this is an
oversimplification; there’s a great deal of translation going
on, as illustrated in Figure 5—1. For example, suppose you
press CTRL—D to invoke the paragraph editor’s DELETE command.
First your computer translates your keystroke into an elec-
tronic code, in this case 004, which is defined by the
American Standard Code for Information Interchange (ASCII,
pronounced ask—key). When ThinkTank receives this code, it
translates it again into the DELETE command that performs the
function you want.
There is nothing magical about either of these trans-
lations. Many of the keystroke—to—ASCII conversions are stan-
dardized, but some are not. For example, pressing the left
arrow key might generate ASCII code 008 on one computer and
164 on another. Similarly, there is substantial flexibility
in the way ThinkTank translates ASCII codes into commands.
You can’t ordinarily do much about the’ way your computer
translates keystrokes into ASCII codes. But ThinkTank gives
you quite a bit of control over its ASCII—to—command trans-
lations, which allows you to customize ThinkTank’s command
keys to your needs, preferences, and computer system. Al-
though we have preconfigured ThinkTank’s command keys to fit
most people’s requirements, there are several reasons why you
might want to modify them. For example, you may be using an
alternate keyboard that contains special keys you want to as-
sign to ThinkTank commands. There nay be special characters
