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

I remember reading this, but don't recall -- perhaps killed off by CA as

of IDMS out there?  Supported by whom?

all gone as immediate GIM descendents, but lots of children alive and well
via PICK and PICK-alikes

Alive as "Reality" at Northgate in the UK, one of the PICK descendents

Is one of these MUMPS?
