I am far from an expert in RMS (unlike Hein), but my very basic
understanding is that global buffers work for both sequential
and index-sequential files.

But to provide value in the form of better performance then:
- the same file need to be accessed by multiple processes
- the access need to go through RMS

Which may have been a common scenario 35 years ago, but
not so much today.

An indexed-sequential file being updated by multiple
processes running some Cobol/Basic/Pascal application
designed 35 years ago is probably the most likely
combo to match those criteria.
