Greetings, I am wondering what is the oldest machine that supports the PLO (Perform Locked Operation) instruction, and whether there are any older machines that are still running supported versions of MVS (aka OS/390, z/OS)?
Phrased another way, is it safe to write commercial applications (targeted for any IBM-supported version of MVS) that require the presence of PLO? Jeffrey D.
