Suppose you are on a z14 running z/OS 2.3. If you invoke the assembler with something like: MACHINE(ZS-3) (which is a z9). Then O'LOCHINZ will return "U" because LOCHINZ is not valid on a z9. At least, that has been my observation when I play around with this piece of code on a z14 running z/OS 2.3 with the parm MACHINE(ZS-3). That's why I wanted to know a z14 only instruction. If O'it was "U", then the code would assemble the STORAGE macro without an EXECUTE=NO parameter. Simple over optimization on my part, but this is my current "learning vehicle" code and I am trying to find "extreme boundries". > > > -- > Shmuel (Seymour J.)
