Thanks for the reply Ted

Yes, I had considered just eval'ing the code - as you surmised, this will be added by trusted users only. Paranoia, an aversion to string evals, and a desire to learn about parsing led me to this post. But evals may yet be the way to go.

HOP::Parser is great but very, very slow.

That is what I feared - good to know

Probably my main reason for looking at a proper parser solution was to be able to handle nested expressions and logic branches (terminology?). I didn't want to waste time going down one road if it was obvious to everybody else that I shouldn't bother.

Given what you've said, I'm going to give it a go, and just see where it takes me.

thanks again
