does subroutine introduce additional delay?

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.

I am trying to write a lot of perl and trying to organize my program in
case I need to modulalize it. Well, I just like
having pretty much all function in sub.
Also trying to learn subroutine..

If a piece of code doesn't get used repeatedly, it doesn't deserve
modularization. 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.
