John, We're almost to the point to begin trying to measure performance improvement, so if I find anything significant I'll post it later, but have you seen the SHARE presentation from Tom Ross where he documents how performance improvements are achieved? It's informative, and can help guide you in what to look for.
As far as other glitches, I posted a message yesterday about the absence of IGYOP messages, and specifically IGYOP3091-W. In further experimenting, we have discovered that it's not just that the message isn't being produced, it's that the code that can never be executed is not being discarded as it was in COBOL 4.2. So, there's no message about it because the compiler is no longer doing what it used to do. We intend to open a PMR in the morning and see what response that yields. Regards, Greg Shirey Ben E.

Hi, All, Has anyone implemented COBOL 5.1 to the point that you have measured the "promised" performance improvements in application code over the same code compiled with earlier COBOL compilers? Any "hiccups" or other glitches or gotchas you'd care to mention with COBOL v5.1? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
