Charles:
I couldn't have said it any better. I also want to use 64bit as I eluded to in my previous note. As I read thru the MVS Extended Addressability Guide I am trying to understand restrictions, especially when you in a mixed Language environment. I have done a lot of looking in the LE Language Guide, Ref and ILC guides and see bits and pieces of 64bit examples and mixed ( working ) language examples. John Ehrman’s 64bit Share.org presentation was excellent as was Ed’s. I am not bashing IBM, but I don't understand why there isn't more information in both areas. I feel there are probably more areas. Mostly because the dinosaurs like us are retiring and information is being lost.

I have not done any 64-bit work in C/C++, but the number of "this is not available in AMODE 64" and "this behaves differently in AMODE 64" notes would give me pause. I have a requirement/enhancement that would be perfect for above-the-bar from C++ but I am nervous about undertaking it that way for that reason. There seem to be in general so many unexpected interdependencies among various C/LE options. I needed to interface to the GSK encryption. That required POSIX(ON). All went well until final testing, when a stupid little utility program that was supposed to be loadable from COBOL suddenly was not. Why not? COBOL can't load a POSIX(ON) C program. Really? Really. In addition to this sort of gotcha be aware of the inherent/documented differences. In 32-bit C, for example, a uint and a size_t are the same thing -- you can pass & of a size_t to a method with uint * in its prototype; but in AMODE 64 C they are not the same thing and you cannot. Don't get me wrong. I love XLC. Could not do what I am doing without it. But AMODE 64 C gives me pause. I would love to hear that I am wrong.
