Fw: Does Ent. COBOL 4.1 generate 64-bit binary arithmetic instructions?
I am a COBOL person not an Assembler person. Don't the grande instructions require a specific architecture level set? If so, that might be why (as others in the thread have indicated), COBOL does NOT do what you are asking about. It would seem a reasonable SHARE requirement for something like - when using *ALL* COMP-5 sending and receiving fields, (and possibly also when using all binary fields with TRUNC(OPT)) then binary, not packed-decimal arithmetic should be used. When such arithmetic is using large binary fields, then grande instructions should be used. This assumes, however, that this would actually provide a demonstrable advantage to IBM COBOL customers.

I did not see anything about it in the updates page in the language reference nor the programmer's guide, but I'm wondering if anyone here knows if the newest release of the Enterprise COBOL compiler will generate grande arithmetic instructions for COBOL binary fields (e.g. will it generate an AG or AGR instruction for adding two PIC S9(18) BINARY fields?). TIA for any info you can provide.

Yes, but it's not exactly a late-breaking ALS -- like, circa 2000. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

If so, that might be why (as others in the thread have indicated), COBOL does NOT do what you are asking about. Since Enterprise COBOL requires z/OS 1.9, it requires the grande ALS. It would seem a reasonable SHARE requirement for something like - when using *ALL* COMP-5 sending and receiving fields, (and possibly also when using all binary fields with TRUNC(OPT)) then binary, not packed-decimal arithmetic should be used. When such arithmetic is using large binary fields, then grande instructions should be used. This assumes, however, that this would actually provide a demonstrable advantage to IBM COBOL customers. The grande instruction set usage can be useful for even S(9) BINARY since it would be a simpler way to handle overflow with multiple operands.
