VERIFY
Abbreviation: V <SHIFT+E>

TYPE: Command
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
OK
SEARCHING
FOUND <FILENAME>
VERIFYING

9000 SAVE "ME",8:
9010 VERIFY "ME",8 (Looks at device 8 for the program)
