The first thing that you should read is the documentation supplied with
Perl.  The document describing subroutines is perlsub.pod.

Subs in Perl are pretty simple.  All arguments to the sub are flattened
to a list and are available inside the sub in the @_ array but be
careful because modifying the contents of @_ will modify the contents of
the original variables.  All return values are also flattened to a list
when the sub ends.
