Radio Shack TRS-80 PC-3

To edit a stored character sequence, switch into the ReSerVe mode and press(sHIFT)and the key under which the sequence is stored.
You can then edit using the Left Arrow, Right Arrow, DEL, and INS keys in the same way as in other modes.
When the last character in a stored sequence is a '@' character, it is interpreted as @f@ when the sequence is recalled. For
example, if you store the string "GOTO 100@" under the 'G' key, typing (SHIFT) and 'G' in the RUN mode immediately starts
execution of the program at line 100. Without the '@' character, you must press (ENTER) after the (SHIFT) and 'G' to begin
execution.
Templates
Two templates are provided with the PC-3. You can use these templates to help you remember frequently used ReSerVe sequences
or DEF key assignments. After you have labelled the programs or created the sequences, mark the templates so you know what
is associated with each key. You can then execute programs or recall sequences using the two-keystroke operation.
For example, if you have one group of programs which you often use at the same time, label the programs with letters and mark
the template so that you can easily begin execution of any of the programs with two keystrokes. You might also store frequently-
used BASIC commands and verbs in the Reserve Memory and mark a template to speed to entering BASIC programs.
Example:
SIN COS TAN ASN ACS ATN
0000000000
RUN NEW INP, PRI. A*A B*B
