Do you mean you're trying to create a "copy" subroutine to use in a program? Something like: 
sub copy( source, destination ) {
    open SOURCEFILE "source";
    open DESTINATIONFILE "destination";
    while (<SOURCEFILE>) {
        print DESTINATIONFILE ;
    }
    close DESTINATIONFILE;
    close SOURCEFILE;
}

If so, then maybe the problem is in how you're opening the destination file. 

open FILE "<$file";

[download]
to read a file 
open FILE ">$file";

[download]
to write to a file, creating it if necessary 
open FILE ">>$file";

[download]
to append to a file, creating it if necessary

Forget that fear of gravity,
Get a little savagery in your life.
