MBCA had a poor mans ISAM that really wasn't all that bad considering it worked on all those platforms. Cannot say I really liked DIBOL all that much but it was compact and relatively easy to learn. Fast forward to the mid 80's on VMS, I even did QIOs in DIBOL on VMS to interact with 3270 emulators.

That jogged a long-forgotten memory.

With RSTS/E DIBOL, you had two ISAM systems, RMS and an earlier DIBOL
specific ISAM system.

I only used DIBOL-specific ISAM at the start of my career, so I have
completely forgotten the details.

Was DIBOL-specific ISAM written to support ISAM on systems running DIBOL
that didn't have RMS indexed files ? Were there such operating systems ?

Like I said, way too long ago and I only used it for a relatively brief
period of time before switching to RMS ISAM.

Does anyone remember enough to fill in the details ?

Simon.
