your previous posts sound like:
* 3 possible values (3-way logic): true or false or neither true nor false
And that is why I said "you guys are good fish." (And then then the Perl police arrived ... :) Just kidding...
and my very original quesiont is:
show me an expression where it can be evaluated to neither true nor false
UNDEF will be 'treated' as FALSE; Larry had to have some sanity somewhere...
( But, UNDEF is not TRUE OR FALSE - it is undefined. )
Just because it can't be coded for at this time doesn't change that. :) -Sx-
