Do you come from C?  It's hardly ever necessary to exit(0) at the end of a
Perl program.

>Can  I use <> instead on open file and then <IN> here

Yes, if you first remove $ARGV[1] and $ARGV[2]; here are some ways:

  my ($from, $to) = splice @ARGV, 1, 2;

  my ($to, $from) = (pop @ARGV, pop @ARGV);  # <-- backwards!

Then you can do:

  while (<>) { s/$from/$to/; print }
