excellent! I liked the break down of the expression...I totally had some of this wrong in my head

this explanations were very insightful and removed misconception that I may have had...that's not to say I will get it right on my next try(s) to modify/learn perl code.

will think of a program to use what I have learn from you...or you can provide me with an idea to utilize these new learnings too...and so expect a little more questions

again Grazie MILLE
