Basic

Note, this is popularly believed to be a Backronym?.  --Vitenka

First I've heard that; query "popularly" --Bobacus

Well, it seems to be the consensus to me, anyway.  I've not seen anyone say that it was identified that way from the start, and I have heard people say it was retro-fitted on top.  I've heard it said that the creator named it basic purely to imply simplicity - but I don't have any facts.  There is definately still some argument over whether it [isn't http://www.wordiq.com/dictionary/BASIC.html] or [is] a Backronym?.
