DYNWTO

Whether to modify MOUNT and/or KEEP messages.

• Mandatory

Valid values are:

• M – Change only MOUNT messages. Default.
• K – Change only KEEP messages.
• Y – Change both KEEP and MOUNT messages.
• N – Change no messages.

Note: If the DYNWTO parameter is used to indicate that mount and/or keep messages should not be modified, the unmodified messages cannot be used to trigger IOA functions, such as DO FORCEJOB or DO SHOUT, that are specified in a Control‑M/Tape rule.

The following messages are modified according to the CNGMSGID and MSGFMT parameters, according to the value specified in the DYNWTO parameter:

IAT5210, IEC501E, IAT5410, IEC502E, IEC101A, IEF233A, IEC111E, IEF233D, IEC501A, IEF234E

The CNGMSGID parameter is described in this table, and the MSGFMT parameter is described in .Step 2.3 – Specify MOUNT and KEEP message format.

If M or Y is specified for the DYNWTO parameter, the keywords PRIVAT and SCRTCH are replaced by the pool name in MOUNT messages for Scratch tapes from Scratch pools.

WARNING: Other products at your site may depend on the format of these messages. Use caution when altering messages.
