Use the VARY ,HARDCPY command to specify the routing codes of messages that are included in the hardcopy message set. You can add to the existing set (AROUT operand), subtract from the existing set (DROUT), or redefine the set (ROUT).
Example:
VARY ,HARDCPY,DROUT=(5,6,9,11-41,43-128)
The system would give the same response if you entered the VARY ,HARDCPY,ROUT=NONE command.
The effect of this command lasts only for the duration of the IPL.
