Ah, the days when ones computer came with at least one programming language option (and oftentimes, two, if you were handy with Debug,)
Of course, back then, many programs were found in magazines & you had the "joy" of typing in 400 lines of BASIC code and hoping you didn't make a typo.
Then there was the REAL PITA of finding out that a given program was actually for a flavor of BASIC that wasn't actually compatible with the one your computer had....
