Abbreviation: V <SHIFT+E>
FORMAT: VERIFY ["<file-name>"][,<device>]
Action: The VERIFY command is used, in direct or program mode,
to compare the contents of a BASIC program file on tape or disk
with the program currently in memory. VERIFY is normally used
right after a SAVE, to make sure that the program was stored correctly
on tape or disk.
If the <device> number is left out, the program is assumed
to be on the Datassette(TM) which is device number 1. For tape
files, if the <file-name> is left out, the next program
found on the tape will be compared. For disk files (device number
8), the file-name must be present. If any differences in program
text are found, the BASIC error message ?VERIFY ERROR is displayed.
A program name can be given either in quotes or as a string
variable. VERIFY is also used to position a tape just past the
last program, so that a new program can be added to the tape without
accidentally writing over another program.
EXAMPLES of VERIFY Command:
VERIFY (Checks 1st program on tape)
PRESS PLAY ON TAPE
9000 SAVE "ME",8:
9010 VERIFY "ME",8 (Looks at device 8 for the program)
