1. Saving
(1) Turn off the REMOTE switch.
(2) Put a tape into the Cassette Recorder.
(3) Turn on the REMOTE switch.
(4) Depress the RECORD button.
(5) With the same command which saves your program, you must give the program a "filename". This is for reference pur-
poses. Your filename cannot be longer than 7 characters. To save the program with a filename, type:
CSAVE
(SHIFT)
"PRO-1
(SHIFT) "
Your program will be saved with the name "PRO-1". You can assign any name you desire, whatever is easiest for you to keep
track of. Also, note that there is a 7-character length limit for your filename. If the name is longer than 7 characters, the excess
is ignored. A good practice is to maintain a program log, which includes the program name, starting and stopping locations on
tape (use the counter numbers), and a brief description of what the program does.
Press the
(ENTER)
key. At this time, you should hear a shrill buzzing sound, and the tape should be turning. Also, the "BUSY"
indicator should light up. This tells you that the computer is "busy" transferring your program from memory to the tape. If
this does not happen, start again from the beginning of the section.
Once the computer arrives at the end of the program, the "BUSY" indicator light will go off, the recorder will stop, and the
"prompt" will re-appear on the display. In order to insure that this has in fact been accomplished, we can read it back into
memory from the tape as explained in the next section.
