Commodore PET User Manual page 135

If the message ?VERIFY ERROR is displayed. it means that the program may
not have been correctly recorded ante the tape. Rewind the tape and try the
VERIFY again. If the error persists. rewind the tape back to the beginning of the
save point. save the program again. and verify the program. If the error still per-
sists. try using another portion of the tape or another tape. To find the problem
you may use the Status Word function (ST). ST tells you where the error occurred
(see ST function).
The VERIFY command can be used in program mode. but this is not a com-
mon practice.
Examples:
122
VERIFY
VERIFY "CLIP"
A$="CLlP"
VERIFY A$
Verify the next program found on the ape.
Search for the program named CLIP on
the tape cassette. and verify it.
Sa me as above.
