Only limited checking is done against the input monitoring token.
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.
The caller must serialize to prevent any delay monitoring services
from being invoked concurrently for the environment represented by
the monitoring token.
This macro supports multiple versions. Some keywords
are only supported by certain versions. Refer to the PLISTVER parameter
description for further information.
