Programming Requirements

1. You must include the IWMYCON and CVT mapping macros in the calling program.
2. The caller is responsible for error recovery.
3. If you specify FUNCTION=CONTINUE, you cannot specify the list form of this macro. With FUNCTION=CONTINUE, IWMMSWCH produces an inline expansion rather than an out-of-line service, so you do not need a parameter list. Registers 0, 1, 14, and 15 are not preserved across the expansion.
4. If the key specified on IWM4MCRE was a user key (8 - F) then primary addressability must exist to the monitoring environment IWM4MCRE obtained. You could do this by making sure the primary address space matches the primary at the time IWM4MCRE was invoked.
5. The caller must serialize to prevent any delay monitoring services from being invoked concurrently for the monitoring environment.
