Unfortunately I need to call a tcl script first to setup my TCL environment. I found this script online but it doesn't seem to create the process so I can enter my STDIN

use strict;
use warnings;
use Sockets;

    $wishbin = 'C:\Progra~1\TclScripts\bin\wish84.exe C:\Progra~1\bin\
+WishSetup.tcl';

    die "socketpair unsuccessful: $!!\n" unless socketpair(W0,WISH84,1
+,1,0);
    if ($pid=fork) {
    print "PID: $pid\n";
    select(WISH84); $| = 1;
    select(STDOUT);

    print WISH84 'source TCL_Script.tcl',"\n";

    # Here is the main loop which receives and sends commands
    # to wish.
    while (<WISH84>) {
        chop;
        print "Wish sais: <$_>\n";
        if (/^quit/) { print WISH84 "destroy .\n"; last; }
    }
        wait;
    } elsif (defined $pid) {
    open(STDOUT, ">&W0");
    open(STDIN, ">&W0");
    close(W0);
    select(STDOUT); $| = 1;
    exec "$wishbin --";
    } else {
    die "fork error: $!\n";
    }
