- Perhaps because the people who designed the doc set didn't ask the right
- questions, or thought that this labelling would be more likely to lead people
- to the right place than one that was precisely correct.
-
- To be precisely correct, RMS implements record structure within files. RMS
- does not implement files. Files are implemented by the Files-11 XQP,
- or (for RSX-compatible volumes) the ODS-1 ACP, or (for tapes) by the
- mag tape ACP.
-
- You will note that Kirby McCoy's excellent book, _VMS File System Internals_
- (Digital Press), says not one word about RMS internals (other than documenting
- various data structure fields which Files-11 maintains for RMS's use).
