I believe the Enterprise COBOL 6 compiler generates code that takes advantage, assuming ARCH(12) is specified.
If you are *not* specifying ARCH(nn) where 'nn' is the architecture level of your oldest machine (don't forget DR!) then you are leaving MSU's on the table. The ARCH(nn) level is two less than the "marketing number": a z14 is ARCH(12), and so forth.
