Hi Monks!

I've been working through a Perl intro book as I want to understand Perl better and use it at work. I have developed this simple test file below that uses regular expressions and tags to pull info from a file. Right now, I have to hard code the file name in the Perl script. I'd like to be able to type the file path at the command prompt to point this script at various files in different locations. I thought that I could perhaps use @ARGV to help do this, but perhaps not. Here's what I've done so far: 
use strict;

@ARGV == 1 or die "Specify a file path\n";

open(FILE, $ARGV) or die "Cannot open file: $!\n";


while (<>) {
    /(\S+)\s+\S+\s+(\S+)\s+(.*)/; #testing regex and tags
    print "$1, $2, $3\n"; #testing printing
}
close FILE;
print "Done!\n";

My thinking is that I could use @ARGV to do something like this from the command prompt: 
myperlscript.pl open, "C:/path/to/file/on_windows_pc/file.txt"

Right now, my program just reaches the @ARGV == 1 line and prints out the die statement. I've tried variatons of @ARGV like @ARGV == 0 and different command line statements too. I must be using @ARGV incorrectly and would appreciate it if anyone could point out the proper way to dynamically point Perl to different files without coding it in. Thank you!!
