Mike: The array lookup is going to be much faster, as the array will be stored in memory, the CHAIN will require disk I/O. However, why not just change a variable in your program (not store the flag in an array)? I think that would be the fastest and most efficient of all! cjg Carl J.

In the initial subroutine I'm setting up an array that I could easily store this flag in. I'm wondering what the opinion is as far as performance-wise which is more efficient, doing the %lookup() on the array or chain to the file? Thanks in advance.
