You can still run z/OS 1.13 on older processor but not take advantage of the newer hardware. (my €0.02) It is also possible to use new hardware features OPTIONALLY. So, if HW >= z10 then exploit_new_features else use_legacy_code. Good example of such approach was z/OS 1.1 - 1.5 It could run on 64-bit machine as well as on 31-bit machines. IMHO the difference between 9672 G5 and z/900 was significantly bigger than difference between z/990 and z9 (z/OS V2) or z9 and z10 (z/VM V6). -- Radoslaw Skorupka Lodz, Poland -- Tre tej wiadomoci moe zawiera informacje prawnie chronione Banku przeznaczone wycznie do uytku subowego adresata.

You can still run z/OS 1.13 on older processor but not take advantage of the newer hardware. They may be taking advantage of newer hardware features, but some features you can't fully utilize until all LPARs have the proper hardware and software levels.

Re: What is a PC Call?
We have discussed elements of this topic over and over again here, chiefly in terms of its difficulties for novices. As Bob Shannon has already noted, it is not at all a new once; but it has to be new to every programmer at some time. When you have a question, look first in the archives of this and the assembler list. (If you pose a question here or there that has been discussed at length recently, you will inevitably get short shrift.) The assembler list is likely to be a better forum for detailed technique questions. They are legitimate here too, but more of the people who can answer them authoritatively hang out there. Let me also offer you the perhaps gratuitous advice to test at least your early code in a sandbox LPAR. It is easy to get PC code very wrong in a way that can compromise an LPAR for use by anyone else, requiring an IPL for recovery.

Re: What is a PC Call?
Great stuff Chris, thank you! The problem I have had with a lot of things like this is that the PoOp describes the hardware in a vacuum, as though z/OS did not exist. (As it probably should.) It is also "non-judgmental" -- never says "this instruction is basically an antique, or is likely to get you into trouble -- use this other one instead." Then the z/OS manuals describe things using z/OS terminology, and it is hard to pull the whole big picture together: you can use this hardware facility thusly in the z/OS environment. There is some whole addressing mode as I recall that the PoOp spends a bunch of time on but that z/OS does not support, so it is basically useless unless you are running (or writing!) some OS other than z/OS.
