Aha. Sounds like you want to implement uploading to a server. CGI.pm has an already well tested upload capability.
This is the form creation

#!/usr/bin/perl
use CGI;
my $query= new CGI;
print $query->header;
print $query->startform(-enctype => &CGI::MULTIPART);
print $query->filefield(-name => 'uploaded_file',
        -default => "C:\Uploads\",
        -size => 50,
        -maxlength=> 80);
print $query->endform;

You'll also need to process the file upload, and thats documented in CGI.pm as well.

#!/usr/bin/perl
use CGI;
my $query= new CGI;
print $query->header;
my $file=$query->param('uploaded_file');
while(<$file>) {
    print $_; # the contents of the upload file
}
