It sounds like ADABAS D is a completely different product? Is ADABAS still in production anywhere-- is it supported by Software AG?

> IDMS Cullinane
I remember reading this, but don't recall -- perhaps killed off by CA as others have been? I'd also guess there are still production implementations of IDMS out there? Supported by whom?

Alive and, uh, well, at IBM with IMS software using DB2 underneath in many/most? cases?

> System 2000 MRI
> TOTAL Cincom
> GIM TRW
all gone as immediate GIM descendents, but lots of children alive and well via PICK and PICK-alikes

> DMS 1100 Sperry-Univac
> EDMS Xerox
> Reality Microdata
Alive as "Reality" at Northgate in the UK, one of the PICK descendents

Is one of these MUMPS?
