The Migration Guide for Enterprise COBOL release 6.1 says:
Compile-time storage requirements are substantially increased compared to prior
versions of Enterprise COBOL. The compiler requires a minimum of 200 M region
size to run.
When upgrading to COBOL V6.x, CA Endevor COBOL Generate processors might need to be updated to increase storage requirements.
Recommend the following as a way to determine the necessary increase:
- Compile a large program (ideally the largest one you can find onsite) outside of Endevor with the old COBOL
- Reduce the REGION size until the compile fails. Note the minimum REGION required by the old compiler (REGION_OLD).
- Do the same thing with the new compiler. Note the minimum REGION required by the new compiler (REGION_NEW).
- Increase the REGION size for Endevor batch runs by the difference (REGION_NEW minus REGION_OLD)
** Remember that REGION= specified in the JOB statement overrides REGION= specified in the EXEC statement.
This means that Endevor users need to remove or change the REGION parm in the JOB cards used when submitting a batch job from Endevor
