See return, perlsub,

See "User-defined subroutines" section in Learn Perl in about 2 hours 30 minutes

See "The Default Array Variables" and Chapter 5 "Functions" in the free book Modern Perl a loose description of how experienced and effective Perl 5 programmers work....You can learn this too.

#!/usr/bin/perl -- use strict; use warnings; ... Main( @ARGV ); exit( 0 ); sub Main { my $file = shift || 'thefyle.xxx' ; my $workbook = create_workbook( $file ); ... } sub create_workbook { my( $filename ) = @_; my $workbook = ...; ... return $workbook; }
