I'm pointing it out: it's not $strings, but @strings

Thank you for identifying that error, I wasn't thinking while typing, and my typing, at its best, is, admittedly, horrendous!

I do understand some of the basics of a loop nested within another loop, but my point was not meant to be that issue. I was reasoning that the design of the script, so as to avoid re-reading the original text file, should be such that, once the original file has been read (and its content stored in @strings), the script should continue running, awaiting further user input, with additional "patterns". Had it been written, for example, with a foreach loop, and terminated after each successful full pass through the elements of @strings, a user would then be obligated to re-run the script (and, hence, re-read the text file) to attempt another pattern.

I'm not familiar with the Llama book, but if this is its final exercise I must presume you've gone through all of it and please don't take it as a personal offense, but I find it a bit surprising that you're still doing all this confusion...

Regarding the "Llama book", it is actually "Learning Perl" by Randal L. Schwartz, et al, and published by O'Reilly Media, Inc. I have been trying to learn Perl, using this book for just 2 months, now, and I don't profess to know all of the information, therein. Do you, by chance, have a different text you would recommend for the purpose of learning Perl basics? If so, I would be willing to try it also.

Thanks, again, for your above comments!
