Restrictions

1. This macro may not be used during task/address space termination.
2. Only a single connection is allowed to be active for a given address space at any given time.
3. Specification of both Queue_Manager=Yes, and Server_Manager=Yes requires that Server_Type=Queue. Specification of Server_Type=Routing is rejected.
4. Specification of both Router=Yes, and Server_Manager=Yes requires that Server_Type=Routing. Specification of Server_Type=Queue is rejected.
5. If the callers recovery routine should get control as a result of requesting this service, the function cannot be guaranteed to be complete. It is possible that a token has been saved in the parameter list where the connect token would reside upon successful completion. This token may be passed to IWM4DIS to prevent the address space from being disabled from future IWM4CON requests, but the token should not be used for other services. IWM4DIS in these circumstances may give a warning return code indicating that no connection was established.
6. If the key specified on IWM4CON is a user key (8-F) or SERVER_MANAGER=YES was specified, then the caller must be in non-cross-memory mode (P=S=H)
7. While not a restriction for IWM4CON, it should be noted that when the key specified is a user key (8-F), the connect token may only be passed to IWM4CLSY, IWMRPT, or IWMMNTFY services, when the current primary matches primary at the time IWM4CON is invoked.
8. This macro supports multiple versions. Some keywords are unique to certain versions. See the PLISTVER parameter description.
