The purpose of auto-reply notification messages is to record in the hardcopy log the fact that auto-reply plans to take action and whether auto-reply does take action. One of the messages is for notification if the reply would be too long for the WTOR issuer. Where the notification messages are displayed depends on the setting of the NOTIFYMSGS statement in the AUTORxx parmlib member. For more information about auto-reply notification messages, see z/OS MVS Initialization and Tuning Reference and z/OS MVS System Messages, Vol 4 (CBD-DMO).
