Why not to do it properly, i.e. work with stdin and stdout?

	perl -pe 'BEGIN { $old = shift || die; $new = shift || die; } s/\Q$old/$new/g' 2003 2004 <infile.txt >outfile.txt

If you absolutelly need a script with 4 parameters and not 2, write a
shell wrapper around this one liner:

	#!/bin/sh
	perl -pe 'BEGIN { $old = shift || die; $new = shift || die; } \
		s/\Q$old/$new/g' "$3" "$4" <"$1" >"$2"

or even a perl wrapper using system(). Left as an exercise.

Mikhael.
