I suspect that some use S0C1 as shorthand, and as you note incorrect, description for program interrupt 1.j It might be that some SPIE routines handle the interrupt, maybe print a message, and then allow it through to the OS. I do still remember S0C0 from the 360/91 days, which doesn’t mean program interrupt 0, though the low bits will be 0000. Dreaded by anyone debugging from a hex dump. > I've written code that distinguished[1] between a S/360 and a S/370 > with a SPIE[2] for codes 1 and 2; the exit assumed that it was a S/370 > if the code was 2. I wouldn’t have thought of that one. Pretty neat.
