Arguments

procedure-value

   Specifies an integer expression with a value of 1 to turn
   procedure verification on, or a value of 0 to turn procedure
   verification off.

   When procedure verification is on, each DCL command line in the
   command procedure is displayed on the output device. Procedure
   verification allows you to verify that each command is executing
   correctly.

   If you use the procedure-value argument, the function first
   returns the current procedure verification setting. Then the
   command interpreter turns the procedure verification on or off,
   as specified by the argument.


image-value

   Specifies an integer expression with a value of 1 to turn image
   verification on, or a value of 0 to turn image verification off.

   When image verification is on, data lines in the command
   procedure are displayed on the output device.
