OK, thanks, that works. The next part of the code involves searching my newly created multidimensional array for duplicate entries but in other positions (and it's a fairly large text file to begin with), which takes a while, which is likely what I was experiencing while not seeing the next (apparently buffered) "print" statements.

I have other questions about efficient searching/matching inside an array, but that's a subject for another thread and I have to go out now :)

Thanks again!!
