I remember a detokenizer for RSTS BASIC-PLUS that's not on that list.

I think it was called a "decompiler" though.  Seemed like magic at the time.

Googling reveals "You may be remembering the BASIC PLUS
decompiler under RSTS.  RSTS BASIC PLUS was interpreted from "push-pop" code.
The symbol table was available in the compiled file, and the correspondence
between push-pop operations and BASIC PLUS source was very close, so you
could get back very reasonable code."

And our previous discussion of it a decade ago:
