Problem:

An Entry point is not found when a PL/I program calls subroutine.

The PL/1 program is executed from JCL:

PGM01.pli calls PLIPROG calls entry point ENTPROG in assembler program ASMPROG.

Returns: 173, ENTPROG not in found...

MFENTMAP (in <ProjectFolder>\\LOADLIB:

[ENTRY-POINT]  ENTPROG     

[PROGRAM-NAME]  PLIPROG     

[SUBPROGRAM-NAME]  ASMPROG

Resolution:

The solution is:

tick in project settings: Search mfentmat.dat before file system

Then the Assembler entry ENTPROG is successfully invoked.
