Hi Rolf,

IIRC there is a hard limit for the length of a regex-string

Other than RAM, I haven't found one yet, I just built a qr// regex from a 1GB text file without alternations and a second from 40MB of text with over 10M alternations.

As you may have seen I added a TL;DR, thanks for the idea!

Regards,

in mind. Since regexes are compiled to op codes hard limits are unlikely.

Hmm probably it's time to include support for TOC = table of content in my wiki add on :)
