You guys are fast.
I've been working through the first examples.
Starting from the suggestions, I wrote several scripts (I did variants with $& for the match and also one that uses substring), but... the "real world" files include lines that are 12,000 characters long, often with no word breaks. When I run the scripts on a test file with short lines, they work. When I try them on the dense-text file, it comes up blank. Am I hitting a 2048-character limit? or is it the lack of word breaks?
Maybe the more recent posts will help. I'll read them and check back.
