Using MPF to retain messages

You can also control which action messages to retain through MPFLSTxx. Thus, you can specify on a message by message basis which messages you want the action message retention facility to retain or not. First, ensure that both MPFLSTxx and AMRF are active (either specified on the INIT statement of CONSOLxx or through the operator SET command). With MPF, you can only retain action messages (those with descriptor codes 1, 2, 3, and 11).

To specify which messages you want to retain or not in MPFLSTxx, you can use the following parameter and its option:

msgid: Specifies the ID or list of IDs for messages that you want to suppress or retain

The option you can specify for the msgid is as follows:

RETAIN®: Specifies whether you want to retain the message(s) identified by msgid.

RETAIN(YES) is the default. RETAIN(NO) indicates that you do not want the system to retain the action message. Thus, with MPF you can indicate which action messages that AMRF retains you do not want to keep for retrieval.
