chartsEngine bug with version 10 of LC

Ah, that was the helpful piece of information I required. I didn’t realize it worked through the string one ASCII character at a time (with neither side being a “number” anymore.)

(With the exception of upper and lower case characters having different ascii but evaluating as equivalent.)

Whew! I knew I had both consumed coffee and taken a nap. I was about ready to ask you to use smaller words.  :- )

One of the things that was throwing me (though I’m sure everyone else was rolling their eyes) was the

because, if I’m understanding this correctly, it is really evaluated as 59 = 59  …. 102 <> empty

I like that "-1” < empty  AND 1 > empty  BUT  0 isn’t lesser/greater/equal to empty.  I’m not sure why this whole string comparison issue hasn’t come up for me before but I’m sure that you will all be thankful that I’m ready to move on to my next question... why is it that the socks I put into the wash aren’t always equivalent  to the socks that come out of the dryer. A rounding issue?
