Thank you for the explanation. I've always had a bit of trouble with the way that was worded but think I get it now.
- Thanks for the responses to my question on this. My first post - what a helpful lot you are!
Flo's search string ((ABC(?=.+KLM))|(KLM.*\KABC)) was great. It was easy to tailor it to the actual strings I was working with, it did just what I wanted and solved my problem. You would probably expect that, seeing how it had been tested by Flo, as documented in the message. I'll admit to knowing little about regular expressions, so I've got some work to do to understand why it works.
SNOBOL4 ... I've no experience with that, though I once enquired about a job using it. I think it was investigating natural language translation. But for this problem I was looking at coding something in a .NET language with its string handling. Fortunately, I've been saved from that.
