SET VERIFY is a DCL command that controls whether command lines and data lines in command procedures are displayed at the terminal or are printed in a batch job log. The information displayed by the SET VERIFY command can help you in debugging command procedures.
SET VERIFY [=([NO]PROCEDURE, [NO]IMAGE)] SET NOVERIFY
Two types of verification can be specified: PROCEDURE and IMAGE.
Procedure verification causes each DCL command line in a command procedure to be written to the output device.
By default, both types of verification are set or cleared with SET VERIFY and SET NOVERIFY. If you specify only one keyword, the other is not affected. If you specify only one keyword, omit the parentheses.
