Restrictions

You can issue IXLFCOMP requests only for IXLLIST or IXLCACHE operations initiated by your own connection.
Only one IXLFCOMP request can run at a time with a particular request token. If you attempt to issue another IXLFCOMP request with the same token while the first is running, your second request fails.
All virtual storage areas passed to the IXLFCOMP macro must be addressable in at least one of the following ways:
- From the primary, home, or secondary address space
- From the PASN access list
- From the DU access list
Any virtual storage area specified on the corresponding prior IXLLIST or IXLCACHE request must still be addressable as it was at the time of the prior request. See the IXLLIST or IXLCACHE macros for the addressability requirements of the virtual storage areas associated with those requests.
If you are running disabled, the parameter list and all storage areas addressed by macro parameters must reside in either fixed or disabled reference (DREF) storage. Furthermore, any virtual storage areas that were specified on the corresponding prior IXLLIST or IXLCACHE invocation must also reside in fixed or DREF storage if the IXLFCOMP caller is disabled.
This service cannot be invoked by callers running as a disabled interrupt exit (DIE).
