That's amazing. I optimized the heck out of my nested loop and it
still runs ten times slower than your array-based algorithm.

However... you're pulling a fast one here. You're getting away with
calling something a boolean when it actually isn't. Apparently
Transcript is letting you get away with this.

"if tSymbolArray[char 1 to 2 of tWord] then"    should really be
"if tSymbolArray[char 1 to 2 of tWord] is not empty then"

Making the change slows things down on my machine from 14 milliseconds
to 18 milliseconds, making it about 30% slower, but still much faster
than anything I could do with repeat loops.
