No, of course I can't use such features and have it still run all the way back to MVS 3.8j. But for basic applications, like diff3 or sed, that just do normal I/O, it can run in any AMODE. Basically if you stick to the capabilities that MVS 3.8j had, then you can write a program that will run in any AMODE, including AM64. BFN.
