I have the source for two basic+ decompilers for RSTS/E.
They are both based on the bpcref code (a cross reference
program that shipped with RSTS/E as source for a while).

You may be thinking of RT-11 BASIC, where the "list" command actually
did exactly that.
No, I'm think of circa '83 VAX-based BASIC-Plus (2?).
