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.)
