I'd take another look at Getopt::Long if I were you, its whole purpose is to handle command line options. If you don't need options, don't use Getopt::Long.

I think it's @ARGV that you're looking for.

#pm.pl
print "Arg $_: $ARGV[$_]\n" for 0 .. $#ARGV;

Sample run:

$ perl pm.pl one two three "four five"
Arg 0: one
Arg 1: two
Arg 2: three
Arg 3: four five
