Not that it's relevant....
..but when I first used BASIC back in 1970 on a PDP-10 on a timesharing 30bps modem on a Teletype, it was BASIC - but only because there were no lower-case letters. Hell, we only had five-bit paper tape, and had to use figure-shift and letter shift....
But BASIC is just the name, because it was basic, and someone thought it was a good name. Anyone who tells you it's an acronym is talking out of their hat. Beginner's All-Purpose Symbolic Instruction Code was retro-fitted later, probably in the late seventies.
Oh - and vi, without a doubt. Actually, vim is even better.
And what is this Apple thing of which you talk?
