[AccessD] multi-platform ASP was: OT: Yee Haw....

In logic either a horizontal bar over a symbol or a vertical bar in
front of a symbol means negation.  Since early keyboards did not have
either character on them but did have the exclamation mark that closely
resembles the vertical bar, the exclamation mark was adopted as the
negation symbol.  Some languages whose origins are based on logic and
not math still use the exclamation mark as the negation symbol even
though keyboards now have the pipe (vertical bar) character.

>>I don't know how long ! has meant factorial in the math world.

For the last 50 years at least, Drew.

Hmmmmm...wasn't really speaking programatically.  I was speaking from
math terms...I don't know how long ! has meant factorial in the math
world.

I'm not sure about this one, Drew, but as an official old timer I'm
pretty sure that ! meant NOT before it meant Factorial. I learned != as
NOT EQUAL in something like 1984-5. So I'm on the side of the demented
whacko. What languages support ! as Factorial? I would have thought such
a rarely used formula would naturally fall outside the language
definition and be implemented instead as a function Factorial(), or left
for you to write.

First of all, what demented whacko
decided that != is 'not equal'?  ! is for factorial.  How does that turn
an equal sign into a 'not equal' sign.  However, <> does make
mathematical sense, because something cannot be both less then, and
greater then another number, so it represents an inequality...at least
more then a factorial does!
