LU07643 and calls to IDMSCOMP and IDMSDCOM

Issue/Introduction
PTF LU07643 documents that any user-written assembler programs which call IDMSCOMP or IDMSDCOM need to have their entry points changed to COMPEP1 and DCOMEP1.
Does this imply that any schemas that reference IDMSCOMP or IDMSDCOM as database procedures also need to be changed?
Environment
Release : All supported releases.
Resolution
There is no need to make changes in the SCHEMA calls. They need to remain as CALL IDMSCOMP & CALL IDMSDCOM. These calls are made by IDMSDBMS not by the user program.
The change is only needed if you have coded user-written assembler programs that directly call and are linked with IDMSCOMP and IDMSDCOM, they would contain a VCON like V(IDMSCOMP) or V(IDMSDCOM).
They need to be changed to V(COMPEP1) or V(DCOMEP1).

**************************
* STEPS TO PERFORM *
**************************
After installing this PTF, you may need to recompile or
link any user-written programs.
The entry point for the modules IDMSCOMP and IDMSDCOM have changed.
Previously the entry points were IDMSCOMP and IDMSDCOM but are now
changed to COMPEP1 and DCOMEP1. Any user-written programs which
which link with IDMSDCOMP or IDMSDCOM and contain a VCON like
V(IDMSCOMP) or V(IDMSDCOM), will get S0C1 if they call those names.
The S0C1 will occur because the user program will branch to offset
zero in the given module. To avoid the S0C1, any user-written
programs with a V(IDMSCOMP) or V(IDMSDCOM) will need to change to
V(COMPEP1) or V(DCOMEP1). Programs that load and call these
these programs will not need to change.
