Restrictions

1. Caller is responsible for error recovery
2. Only limited checking is done against the input monitoring token.
3. If the key specified on IWM4MCRE was a user key (8-F), then the primary addressability must exist to the performance block IWM4MCRE obtained. This condition is satisfied by ensuring that current primary matches primary at the time that IWM4MCRE was invoked. If this service is invoked in a subspace, the condition may be satisfied by ensuring that the performance block is shared with the base space.
4. The caller must serialize to prevent any delay monitoring services from being invoked concurrently for the environment represented by the monitoring token.
5. This macro may only be used on z/OS V2R1 or higher.
