Two issues (or questions):
1) the license for CpcRegul does not allow commercial use (PCRE doesn't have
that limitation) -- really, this issue alone warrants coming up with an
alternate solution.
2) CpcRegul makes use of Babel, which has this in its documentation:
>Babel is a meta compiler. From a language definition document, it builds
>the tables of a compiler (lexical, syntactic and semantic) and store them
>in a binary file. A special module, included in the final program, reads
>this file and then can compile texts of the language.
That sounds like it's good if you have 1 or 2 thing you'll be matching,
given that it has to **create** binary files. But, if you want to use it all
the time for big AND small things, then it sounds cumbersome. I've recently
been using Ruby which has regular expressions built in, and it's nice to be
able to do matching all the time with no thought.
My sense was that it would be worth having a DLL interface generated for
PCRE, and then write a couple wrapper functions that make it easy to use it
frequently for big and small needs.

Doug,
Have you considered the subsystem "CpcRegul"?
http://www.zinnamturm.de/#CpcRegul
It can search any regular expression in texts, and I have been using it
without problems for several years. Its syntax is not exactly the same
as PCRE, but very close. It can also replace found patterns by strings.
CpcEverywhere (
http://www.zinnamturm.de/#CpcEverywhere) uses the same
search engine to do pattern matching in files.
Cheers.
Gérard
