I've recently returned to using perl after a year or so away.

s/perl/Perl/

I therefore just tried running the following

use strict;
use warnings;
print "arg0=" , $ARGV[0], "\n", "arg1=", $ARGV[1], "\n";

No matter what I pass on the command line, single quoted , double
quoted or unquoted I never get anything in $ARGV[0] or $ARGV[1].

U:\PerlScripts>argv.pl "aaaaa" "ddddd"
Use of uninitialized value in print at U:\PerlScripts\argv.pl line 3.
arg0=
Use of uninitialized value in print at U:\PerlScripts\argv.pl line 3.
arg1=

The only command I can get to work is as follows

U:\PerlScripts>perl -le "print $ARGV[0]" "dddddddddd"
dddddddddd

U:\PerlScripts>

Having been away from perl for some time I guess I'm missing something
fundamental here. Perl is ActiveState 5.8.3

Most likely, this has nothing to do with Perl but with the fact that the
file association for .pl is not correctly set up (in the Windows
registry).

Make sure the following match the output of the same commands on your
system.

E:\> assoc .pl
..pl=Perl

E:\> ftype Perl
Perl="C:\opt\Perl\bin\perl.exe" "%1" %*

My guess is that on your system, the trailing %* will be missing. You
should be able to fix that. You can get help on the ftype command by
typing

E:\> ftype /?
