Reserve Mode - Radio Shack TRS-80 PC-3 Owner's Manual

*
To execute the program, instead of typing RUN 80 or GOTO 10, you need only to press the
~
key and then the letter
used as a label. In the above example, pressing
~
and then 'B' would cause 'SECOND' to appear on the display.
When DEF is used to execute a program, variables and mode settings are affected in the same way as when GOTO is used. See
Chapter 8 for details.
ReSerVe Mode
Another timesaving feature of the PC-3 is the ReSerVe mode.
Within the memory of the PC·3, 47 characters are designated for "Reserve Memory". You can use this memory to store frequently-
used expressions, which are then recalled by a simple two-keystroke operation.
NOTE: You store the strings in the ReSerVe mode and recall them for use in the RUN and PROgram modes.
Try this example of storing and recalling a reserved string.
Switch the PC-3 into ReSerVe mode by moving the slide switch to the RSV position.
Type NEW, followed by the
(ENTER)
key. This will clear out any previously stored characters in the same way NEW clears out
stored programs in the PROgram mode.
Type
(SHIFT)
followed by 'A'.
