Well, High Level Assembler for z/OS & z/VM & z/VSE Programmer's Guide, High Level Assembler for z/OS & z/VM & z/VSE Programmer's Guide, SC26-4941-08, gives the for the MACHINE and OPTABLE options, and you can test the optable with &SYSOPT_CURR_OPTABLE. PoOps breaks things down by feature set rather than processor, so you'd have to piece things together; I don't know of a single document listing opcodes explicitly by processor. -- Shmuel (Seymour J.)

Is there a list of instructions which only work on a z14? Why am I asking? Because I want to do some conditional assembly based on whether code is assembled to run on a z14. I don't want to dual path. This will be a source distribution, so dual pathing should be unnecessary. I.e. I am "dual pathing" the source code rather than the executable. -- This is clearly another case of too many mad scientists, and not enough hunchbacks. Maranatha! <>< John McKown
