Derek, that's hardly believable 
Seeing as how one function requires a string compare and one uses an
array access, i dont see how they can return with the same delay.
The delay i've measured is three times longer but it's still not
that long so it's not going to be a 'major' issue most likely.
I just dont like changing something that adds a delay unless the
increased functionality is worth it. In my code i use an added atom
test that adds a little time too.
No worries though, if it's just my computer then dont worry about
it at all
Take care,
Al
And, good luck with your Euphoria programming!
