Looks to me like there isn't much reason to have the subs larger or small in the first place.

IMO there are generally two reasons to have a subroutine.

  1. The code will be executed multiple times in the script.
  2. You want to modularize the code for re-use

Adding subroutines where there's no clear reason for one just adds confusion to a script.

That being said, if you do break things up into subroutines, it's generally good form to ensure that each subroutine does one thing and one thing only. Short and too the point.

A run-on subroutine suffers from the same disease as a run-on sentence.

I recommend reading Code Complete by Steve McConnell (M$ press). It a very good book on coding style and best practices.
