Apparently PowerBasic was the successor to Borland TurboBasic and complied to a native executable. So this wasn't an interpreted 'line number' Basic like our kiddie computers. It also probably had the Borland Windows GUI stuff.
(However it wouldn't surprise me if older 'line number' programs still mostly worked. iirc VB6 also supported this.)
