You must include the IWMYCON mapping macro in the calling program.
If the key specified on IWM4MCRE was a user key, then
either primary or secondary addressability must exist to the performance
block IWM4MCRE obtained.
If you specify MONENVKEYP=VALUE, then the caller must be in supervisor
state or have PKM authority to the key specified by MONENVKEY.
If you specify MONENVKEYP=UNKNOWN, then the caller must be in
supervisor state or have PKM authority to key 0.
The caller must serialize to prevent any delay monitoring services
from being invoked concurrently for the environment represented by
the monitoring token.
Only limited validity checking is done on the input monitoring
token.
