Please consider following perl code:

if( @ARGV ) {
    $out = shift(@ARGV);
}

open(OUT, ">$out");

The argument passed is C:\some_dir\some_file
Does OUT have any relation to $out.  Does anything get written to some_file in the "open" statement.  What is the "open" statement doing?

The doc on the open function should answer your homework question.

perldoc -f open

BTW, it's not a homework question. I'm not in school.

Think of a filehandle as a reference to a physical file (not always the case).

FishMonger's suggestion and running your script should answer your other questions.
