Waaay...Back when I occasionally taught BASIC and APL, I always heard (Where?) that the "?" meant "What Is". Like: ?2+2 (What is 2 plus 2) ?2^16 and that this was intended to be used in "Immediate Mode". Some BASIC I used to use (Hmmm..??) would accept the "?" in program input lines, like: 100 ?"The Result is ";A but if you did LIST, it was shown as PRINT. That WAS a while ago...
