I have a confusing issue with using COBOL E15/E35 exit programs where the exit programs dynamically call application-specific subroutines in a JCL SYNCSORT. The issue is from which library the exit programs are actually loading the dynamically called subroutines. It seems that the dynamic subroutines always load from LINKLIB, and not from STEPLIB or JOBLIB. What I EXPECTED to happen was that the version of the dynamically called application-specific subroutines in the STEPLIB or JOBLIB would be used, not the version in LINKLIB.
The JCL sort in question has a STEPLIB pointing to a small PDS with application-specific versions of certain dynamically called subroutines. The MODS statement is coded like this: MODS E15=(EXITE15M,2048000,,C),E35=(EXITE35M,2048000,,C) When each of the exits (both are compiled with Enterprise COBOL V5.2) EXITE15M or EXITE35M is called by SYNCSORT, the only version of those exit programs available is in the LINKLIST in a global application library. Both exits dynamically call one of the application-specific subroutines as one of the first things that they do. The application-specific subroutine performs a WTO as part of its normal operation (ROUTCDE=11,DESC=7) to allow identification of which version of the subroutine was actually loaded and executed. Even with a STEPLIB (and I also tried a JOBLIB) pointing to a library with DIFFERENT VERSIONS of the application-specific subroutine than are in the global application library in the LINKLIST, only the GLOBAL VERSION in the LINKLIST application library is ever used, as evidenced by the WTO message generated. Is this a misunderstanding on my part of how dynamic calls from a MODS exit program should work, or is this a potential issue for a call to SYNCSORT support? SYNCSORT level is 2.1.6.0N, z/OS V2.2.
