If you've got CICS, how about using a 64-bit container? This feature is available starting in CICS Transaction Server Version 3.2 (in 2007), when containers were moved above the bar. They should be quite transparent to your 31-bit application. (Just call CICS and let it do the lifting.) It's hard to say what CPU time you'd see, but my guess is it'd be closer to the 10 minute number for a comparable run. ....64-bit C (or C++) is another option, as pointed out. No, it's not that expensive. There are at least 3 commercial compilers available.), ....64-bit Java is a possible option. Java is a standard z/OS feature (no additional license charge) and zAAP eligible. (Can Enterprise COBOL's INVOKE statement call 64-bit Java? I'll have to check that.) ....64-bit Assembler is still an option. That's a standard z/OS feature, too. ....Certain other middleware products (besides CICS) may be relevant. WebSphere Transformation Extender comes to mind as a possibility, for example. ....There are undoubtedly ways to do this (handle 10G) using multiple address spaces (~6+) that collaborate. Might even be some workload advantages to that, actually, depending on the situation. All that said, please get your requirements for 64-bit COBOL into IBM. (And PL/I, for that matter.) IBM is listening. The more information you can provide about your situation, both technical and non-technical, the better. Yes, as alluded to previously in this thread, LE is very much a technical factor here. Any path (how, and thus partly when) to 64-bit is customer-driven, not religious or political. - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Based in Tokyo, Serving IBM Japan / Asia-Pacific E-Mail: [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
