then this raises an interesting question (for me at least)

i should probably test this myself (and probably will but love
discussion ... and have a deadline breathing down my neck ;)

if i make a function, and encapsulate it in a file, then
make calls to that function from a script which had been
compiled using perl2exe...
would the whole program still work?
could i change the required and encapsulated function as needed?
is this the basic concept behind a DLL file in windows?
    or are there more to them?

i've not got a lot comp-sci so i'm trying to pick up advanced topics
in programming on the fly, while simultaniously learning the basics
i'd love some help me in gaining a deeper understanding of the whole system
