My customer wants to start the migration to Enterprise COBOL V5.2. I know V6.1 is out but we need to get going on this project. I have deleted all COBOL compilers below Enterprise COBOL V4.2 from their systems. I worked with an applications representative and they have decided on the compiler options they want. Load library conversion to PDSE is complete. Analysis of load libraries looking for OS/VS COBOL and determining which of those load modules are still in use has been determined and they will be recompiled either with Enterprise COBOL V4.2 or V5.2. I know there are some others things to look at but these are done.
If there is a COBOL specific web site for these types of questions that would be a better place for these questions please let me know. Some users have been playing with the new compiler and comparing it with Enterprise COBOL V4.2. They have picked a few current programs and compiled, linked and run them. One load module was 3-4 times as big when compiled with OPT(2). With OPT(0) it was %50 larger. Is this a typical increase in size for V5.2 compiles? Has anyone noticed a difference in CPU execution time either way? A size increase would not be a big problem but a large increase in CPU time would be.
