   1.$ SAVE_PROC_VERIFY = F$ENVIRONMENT("VERIFY_PROCEDURE")
     $ SAVE_IMAGE_VERIFY = F$ENVIRONMENT("VERIFY_IMAGE")
     $ SET NOVERIFY
        .
        .
        .
     $ TEMP = F$VERIFY(SAVE_PROC_VERIFY, SAVE_IMAGE_VERIFY)

     This example shows an excerpt from a command procedure. The
     first assignment statement assigns the current procedure
     verification setting to the symbol SAVE_PROC_VERIFY. The second
     assignment statement assigns the current image verification
     setting to the symbol SAVE_IMAGE_VERIFY.

     Then, the SET NOVERIFY command disables procedure and image
     verification. Later, the F$VERIFY function resets the
     verification settings, using the original values (equated to
     the symbols SAVE_PROC_VERIFY and SAVE_IMAGE_VERIFY). The symbol
     TEMP contains the procedure verification before it is changed
     with the F$VERIFY function. (In this example, the value of TEMP
     is not used.)

   2.$ VERIFY = F$VERIFY(0)
        .
        .
        .
      $ IF VERIFY .EQ. 1 THEN SET VERIFY

     This example shows an excerpt from a command procedure that
     uses the F$VERIFY function to save the current procedure
     verification setting and to turn both procedure and image
     verification off. At the end of the command procedure, if
     procedure verification was originally on, both the procedure
     and image verification are turned on.
