If the expiration date of the indicated data set is to be ignored and the program has authorization to write on the data set, enter REPLY xx,‘U’ in response to this message.

If the expiration date of the indicated data set is to be honored or if the program is not authorized to write on the data set, enter REPLY xx,‘M’ in response to this message. If another volume can be used, that is, if the program originally requested a SCRTCH or PRIVAT volume, the system will then request that a new volume be mounted. However, if another volume cannot be used, the system will end the job step. Attention: If dev is a direct access device, do not enter REPLY xx, ‘M’ unless you have the proper authorization. Instead, use the CANCEL command to end the job step and notify the system programmer that the expiration date on the data set has not been reached.

Normally, the operator should end any job attempting to update a system data set or otherwise authorized data set if this message is issued. However, the operator may respond with REPLY xx,‘U’ if so instructed by a programmer with proper authorization. An authorized programmer desiring to update a system data set should notify the operator of his intentions and make sure that no other concurrently running job can have access to the data set. If you want to remove expiration date protection from the data set, specify LABEL=RETPD=0 in the JCL next time the data set is created. Subsequently, the message will not appear.
