" Of course learning regular expressions might take a long time....."

yup!...my wife did DOS for years...she can almost think in it...but I never got the hang of command-line expressions and the like. I think it's a matter of wiring.....but I can look at a request like Gene's and create the search parameters necessary to FIND a piece of data or a program, and I can make programs work, though I have NO idea how they are constructed. (It's like being able to drive almost any vehicle, while barely understanding how to change the oil! *grin*...we all have our little skills)
