On Windows, you just double quote command line args that have spaces. @ARGV should be a read_only thing for a user. 2 simple Perl scripts and how they can interact: 
#!/usr/bin/perl -w
use strict;
#file: testargv.pl

my $parms = 'a b c abc "some gizmo" d32';
print `perl argv.pl $parms`;

__END__
prints
a
b
c
abc
some gizmo
d32

===== file argv.pl ========
#!/usr/bin/perl -w
use strict;
#file: argv.pl

foreach (@ARGV)
{
   print "$_\n";
}

==example of command line input to argv.pl ====
C:\TEMP>perl argv.pl "some thing" "some other thing" d x "xy z"
some thing
some other thing
d
x
xy z
