i've got a short program that is fully functional

it opens a (comma delimited) file from the command line
and puts it into a multi-dimentional hash of arrays

  $DATA                       = HASH
  $DATA{$key1}                = HASH  
  $DATA{$key1}{$key2}         = ARRAY
  $DATA{$key1}{$key2}$value = 'data element'
     
so what we have is one file translating into a relatively 
complex data structure.  

I have this file working and would like to 'encapsulate it'

i'd like to start the next step of the program in a blank 
file ... 

   i'm writing for advice on how to do this (although i 
have assumptions)

   the question then is: 
what conditions must be in place in order to turn a 
complete program into a 'magic box' or function that
can be included in another program?

   note: if i find a good answer first i'll fill it in 
i always ask here first 

   i'm thinking it will be along the lines of:

   require 'ReadInFromFile.pl';

one of the main things i'm worried about is compile-time.  
Because i am working on win32, writing utilities for 
non-technical workers this program MUST be executable

i've got a compiler (freeware, named perl2exe) and i 
want to make sure that when this becomes an EXE it will
incorporate the 'ReadInFromFile.pl' file.
