But I'll bet they mean only those which use problem state, but not supervisor state, instructions. When the program does something like an SVC or PC, I'll bet that some sort of native code routine which implements the standard z/OS API function runs; unlike Hercules/390. I.e. the API function "marshalls" the z/OS API data; invokes the needed host OS functions; then "unmarshalling" the results back to the application. A bit like Wine does for the Windows API under Linux, but with instruction emulation thrown in. Say, as if you could run Wine on Linux/ARM with QEMU emulating the x86 instructions. > > Mike Shaw > MVS/QuickRef Support Group > Chicago-Soft, Ltd. > > -- Heisenberg may have been here.
