Yes, there is a non-trivial amount of work done setting up a function call; however, since you are only calling it once that isn't a big deal. My rule of thumb for creating functions is: I need a function if I use this code repeatedly or the code is complex and ruins the flow of the main script. In general, the later is rare. snip > I am trying to write a lot of perl and trying to organize my program in > case I need to modulalize it.

Also, you said in an earlier post that you were using a global variable (@bad I think), using global variables defeats modularization and is bad programming practice to boot. -- Chas.
