Thank you for this advice. I was almost sure I was using qr// somewhere in the code...I even remember making some recent use of it. But I went back and looked at that subroutine, and then searched through all parts of the script, and found that I had made very little use of qr//, and none in portions I had recently worked with. What the composeRegex subroutine is doing is basically my own version of quotemeta. As it was sometime back that I labored through that portion, I know I had tried quotemeta and had some issues with it, which is why I ended up doing my own thing--but I don't remember now what the issues were. It probably had something to with characters that I did not want to have escaped that quotemeta would have escaped.

I will consider rewriting that portion using qr//. However, I do wonder if that will gain much on the time, as it only executes once per regex, maximum of five times for the entire script run. The time savings would have to be in how the regex was applied during the matches.

I will give it a try--but that part is a bit complex, so I'm not sure yet how it will work out.

Blessings,
