"BASIC-PLUS" and "BASIC-PLUS-2"
are very different beasts. (I haven't
seen BASIC-PLUS-1 before, that wasn't a normal designation but the
meaning is obvious.)
BP was a P-code ("push-pop code")
incremental compiler. It runs only
on RSTS.
BP2 was a regular compiler; it would produce object
files which you'd
feed to TKB to get your RSX-format executables. It ran on RSTS, RSX,
and VMS.
It also ran on TOPS-20 (though I swear that I thought the name there was
BASIC-PLUS-4, nothing I've seen since 1984 backs me up on that). There,
it was a replacement for the second Tops-10 BASIC; the first was not
portable to the newer OS.
(NB: The first Tops-10 BASIC was the one learned by Messrs. Allen and
Gates, of course.)
