The LOAD command transfers a program from cassette tape or
disk into the VIC's memory, where it can be used or changed.
LOAD FROM TAPE
If the program to be LOADed is the first one on the tape, all you
have to type is the word LOAD by itself. Unless the PLAY key was
already down, the VIC answers with the message:
PRESS PLAY ON TAPE.
Once the recorder has been started, the VIC says:
OK
SEARCHING
FOUND
LOADING
At this point, any program that had been in memory is lost,
because the new one has begun to take its place. (If you use the
ffflf Key to halt the LOAD there will likely be a spot in the
program with garbage, just at the point where you stopped it.)
Once the program has finished the LOAD, the VIC says:
READY.
