This is okay.  I like it, and it isn't that hard to understand.  I 
learned it from what you showed me and could guess at it's meaning.  How 
do I drop a character off the end of the array/sequence?

I am such an idiot!  I had integer Key, and sequence Text.  I put 
integer Key where sequence Text belonged, like this:

ColorLocatePrint(14, 1, 1, 1, Key)

instead of like this:

ColorLocatePrint(14, 1, 1, 1, Text)

No wonder I was having such problems!
