This command checks the program on tape or disk against the
program in the VIC's memory. VERIFY is normally used right after a
SAVE, to make sure the program was stored correctly on the tape
ordisk. VERIFYing a program after it has been LOADed is useless,
since the same incorrect program could be in both places. i
When you tell the VIC to VERIFY, this message shows:
PRESS PLAY ON TAPE
Once the tape is moving, the VIC checks the program against
memory, reading until the end of the program. If the copies match,
the VIC says:
OK
READY. '
If there is a problem, you will see this message: .
7VERIFY ERROR
In this case, you should immediately SAVE the program on a
different tape or disk and try again.
The format of the VERIFY command is similar to the LOAD
command. A program name can be given either in quotes or a string
variable, and the VIC will search for that program. If a comma and a
device number follow the name, the VIC will look at the device
designated.
VERIFY is also used to position a tape just past the last program,
so a new program can be added to the tape without over-writing an
older one. Just VERIFY with the name of the last program there; the
VIC searches, checks the program, and stops with a VERIFY
ERROR. However, your program is still in memory, and now the
tape is at a blank spot. You can SAVE without worry.
