T-VERIFY

Compares two tapes and reports any data mismatches.

Command Class

TCL-I command.

Syntax

T-VERIFY channelA channelB

Syntax Elements

channelA/B Channel assignments previously made using ASSIGN, specifying the units containing the tapes to be compared.

Comments

Before using T-VERIFY, you must use ASSIGN to attach the required tape units to the port and give them channel letters.

T-VERIFY should be run after a T-COPY to check that the copy was successful. It ignores the date and time in the tape label as this is updated by T-COPY.

If multiple reels are verified, take care to load them in the correct sequence.
