Hi everyone,
I am starting to write a number of perl programs. Most relate around a
particular application which has numerous environmental variables. The
variables can be set from a number of places and those places have a
hierarchy as to which takes precedence over the others.
I have therefore written a perl sub routine that builds up a hash of
environmental variables and their respective values and then use them in
my scripts.
I no longer want to maintain this sub routine in every script I write
regarding this application.
Do I need to create a module and put this routine in it?
If so how?
Do I declare it as a function in the module and then call it from my
other scripts?
All help as usual gratefully appreciated.
