That's WSU (Workstation Utility) and it started back on the S/34 and continued through the S/36. It was no longer supported after the S/36 and was was one of the very few things that did not come across to the 400.
OK, this is for people with /34 (and maybe /36) experience.
I was going through some old sources that had been parked in the 'not in use' folder when I came across some sources of a type I don't recognize.
They came across when we did the /36 to /400 conversion in 1988 and were desginated UNS36 type by the conversion.
They sort of look like rpg, but they have J,T,S, and D specs in addition to C specs and the C specs have a few extra op codes like PUT and PUTS.
Can anyone ID the source type?
