To assign a phrase to a Reserve key, enter the RESERVE mode (press
I"'"'
I@]) and use
the Reserve Select key to select the group U. II, or 111) in which the phrase will
be
stored. Then
press the appropriote Reserve key ( !
. ".
# .
S. %. or
&).
Depending on which Reserve key you
pressed. the d isplay will appear something like the following:
I
FS:
RESERVE
!The number following the F. six in our example, represents which key was pressed.) When this
prompt appears you may key in the phrase to be stored. As an example type the following:
This phrase is
nO\V
associated with the Reserve key you selected.
Let's test t his. Return to the RUN mode by p ressing the MODE key. Press the Reserve key
you used in our exc;imple. The display \viii now show the command just stored:
I
RUN
RUN
100_
If you press the ENTER key the computer will attempt to run a program at line 100. The
advantage of the Reserve key is that you don't h ave to type an entire command each time you
desire to issue
it.
A special notac.ion 1:1llowed in the Reserve mode could have saved us some trouble in the
previous example. This notation is the use oi the@ (At sign) to represent the EN' T ER command.
If we had assigned t he phrase "RUN 100@" to our Reserve key, execution of the program would
have begun as soon as \ve returned to the RUN mode and pfessed the Rescfve key. To demon ·
strate this, enter the following sta tements as line 222:
222 BEEP 5,50: END
Now enter the RESERVE mode and define one of · t he Reserve keys using these keystrokes:
(Notice that the [• •n•I keystroke is still required to define the Reserve key itself ) .
Return to the RUN mode and press the Reserve key just defined, You will observe that the
ENTER keystroke after the Reserve keystroke is now superfluous.
Actually our noisy example could have been accomplished by assigning the phrase:
BEEP 5.50@
directly to a Reserve key. Try it.
B. Identifying Reserve Keys
As you increase your use of the Reserve keys, you \Viii want to remember which key has
been assigned which function. The PC-i 500A allows you to store three strings of characters (one
for each group of Reserve keys} which identify t he functions of the keys. These strings are
