CALLLIBS support puts restrictions on the use of the CALL and NCAL parameters. Processing of the CALL and NCAL parameters in releases of SMP/E that support CALLLIBS (which includes all currently supported releases of SMP/E) is different from processing of those parameters in previous SMP/E releases that did not support CALLLIBS.

Before CALLLIBS support, NCAL was a default parameter passed to the link-edit utility. However, you could use the link-edit UTILITY entry to pass the CALL parameter instead.

With CALLLIBS support, there is no way to directly tell SMP/E to pass the NCAL or CALL parameter. SMP/E ignores any specification of NCAL or CALL, and instead checks for the CALLLIBS subentry in the load module's LMOD entry to determine which parameter to pass to the link-edit utility when linking the load module.
