You must include the CVT and IWMYCON mapping macros in the calling
program.
The caller must serialize to prevent any delay monitoring services
from being invoked concurrently or subsequently for the environment
represented by the monitoring token
Do not invoke IWMMDELE while in a RTM termination routine (resource
manager) for the task owning the monitoring environment since MVS™ will have its own resource cleanup
routine and unpredictable results would occur. It is legitimate to
use this service while in a recovery routine, however, or in mainline
processing.
