I know all interrupts are masked, but does the program receive control under normal Standar Linkage Conventions (ie - R14 has return address) or is the return PSW stored somewhere? And if the return PSW is stored somewhere, then where is stored (I assume it's in NUCON)? On a different note, I am trying to get a console beep WITHOUT that funky "RRRIII....IIINNN....NNNGGGG" message generated by CP (or "BEEEEEEEPPP" if you are on a XA system). I am using SIO with a CCW control code of X'0B' to generate a console printer ring ... is there a better/easier/harder way that doesn't generate that message by CP? --- Hypocrisy is the Vaseline of social intercourse.
