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...
