COBOL/PL1 or C/C++? It makes a big difference. C/C++ (and MetalC) will use the latest and greatest architecture instructions for ARCH(8),TUNE(8) (at V1R10, for z10) or ARCH(9),TUNE(9) (at V1R12 for z196) compiler options. Enterprise COBOL never does. I don't have access to Enterprise PL1, so I can't say what it uses.
