Re: Location of forms code in z/OS manuals

That's possible. There has been a title key in every PDF from IBM that I looked at, but that's a very small sample size. I may have to resort to parsing the title page. Thanks. -- Shmuel (Seymour J.) Metz http://mason.gmu.edu/~smetz3 From: IBM

Re: Location of forms code in z/OS manuals

That's true for current z/OS but not true across the board. At least the PDF from IBM has title; the ones from bitsavers doesn't even have that :-( -- Shmuel (Seymour J.) Metz http://mason.gmu.edu/~smetz3 From: IBM Mainframe Discussion List

Thanks. Not sure if that would work, because I suspect that GPR 0 when my C++ code starts actually executing is no longer the GPR 0 on entry to CEESTART. Charles -- For IBM-MAIN subscribe / signoff / archive access

XLC defines a macro __R1 in stdlib.h. It is the contents of GPR 1 on entry to the program. Looking at stdlib, it is #defined as __gtab(12) -- or there may be further #defines farther back -- that is as far as I have researched. I am guessing __gtab() is a magically-defined internal function. I
