hey, man--where can I find documentation on this li'l procedure?! I mean, what are the underpinnings--what made that work?! What function of UNIX allowed you to do that? Is it built in to the echo function or can I use the :#:# function with other commands such as printf?

If you have more information or could direct me, that'd be great.

Your solution worked like a charm though; YOU'RE THE MAN!!!

I appreciate it, Frank.
