Well thanks, Brian :-D ...I'm glad you described WHERE to find it on the 
keyboard.
I totally overlooked it, since on my keyboard it appears "broken" so 
it's kind of like a thin ":". I did not realize that it would result in 
a solid vertical.
I also see how that drastically changes the output.

Sorry 'bout the shoving,

Michael
