Two corrections: 1. At several points in this thread I think I may have said "facility bits in the CVT." I wuz of course confused. Make that "facility bits in the PSA."
2. My last bullet below is muddled. Make that "before I start relying on ARCH(12) and therefore need to distinguish it from ARCH(11). As I am currently tentatively relying on ARCH(9) I have about six years ..."

That is what I am using. > What are you actually trying to accomplish with the tests of the > facility bits to determine machine? I like Kirk's approach. I have code that works now using CSRSI and a machine type lookup table, but I think I am going to switch to Kirk's approach because - I think it should work more reliably for zPDT and Hercules. (I know z/OS is not licensed for Hercules, but I hear rumors that some people may be running it there, and my job is writing code that works, not enforcing IBM's license terms. - I think it may be a better solution under VM. - It is a somewhat better approach for the situation where code written and shipped today is running on some future IBM machine. My current code says "if you don't recognize the type, it must be new and therefore okay." Kirk's approach will presumably return ARCH(11) for an ARCH(12) machine. All I need to do is update Kirk's code before I start relying on ARCH(13) and therefore need to distinguish it from ARCH(12). As I am currently tentatively relying on ARCH(9) I have about eight years ... ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
