a little help with "find" script

[Timothy Miller]

Thankya Mike,

If I understand you correctly, my script probably works right, might be a little kludgy. Another way to end the search is to look for "not found" in the result.

Hope I got that right.

I'm still studying your foundChunk script.

Cheers,

Tim
