Reserve Mode - Radio Shack PC-2 TRS-80 Owner's Manual

For details on using the PC-2 as a calculator, see Using the PC-2 As A Calculator later in this manual.
RESERVE Mode
To enter the RESERVE Mode, press
(SHIFT)
(MODE) . RESERVE will appear on the Display.
In this Operation Mode, you can assign commands, statements, or values to any of the Function Keys (
CID
~
CEID )
in any of the three Reserve Modes
(I/II/III)
for a total of 18 different Function Keys. To go from one
Reserve Mode to another, press
CIJ
and the Display will change from
I
to II to III.
For instance,
CID
can be assigned one value in Reserve Mode
I, a different value in Mode II, and still another
value in Mode III.
To use a Function Key which has two or three values, press
CIJ
to change modes, then press the appropriate
Function Key.
Any value, statement, or command which the PC-2 recognizes can be assigned to a Function Key. You'll find it
most convenient to assign common command statements (such as RUN or TIME) which you might use very
frequently. You might also assign long mathematical functions or command lines to a key. Then, instead of typing
them over and over, just put the Computer in the appropriate Reserve Mode and press the proper Function Key.
The value assigned to a Function Key can be any number of characters in length up to a maximum of 77.
However, the total number of characters for all 18 Function Keys cannot exceed 77. When the maximum number
of characters is reached, Error 13 will result. Press
(ENTER) .
The value will be assigned and the PC-2 will return to
the Ready prompt.
