When the CALLPROG function hits a problem on loading or executing, this message displays the modules and entry point (for languages that support more than one entry point per module) and the linkage type.
The task ends.
See the associated messages., which might be PWX-00351 or PWX-00352, for problems on loading the module, and messages PWX-02667, PWX-02668, and PWX-02676 for problems on executing the external routine.
