- That's just about perfect.  I just need a way to get rid of the quotes.

try the following instead.. (using eval and set, as someone else pointed
out..)

	#!/bin/sh
	#
	OIFS="${IFS}"
	IFS="${IFS},"
	while read ln; do 
	    eval set -- $ln
	    echo "$1:$2:$3"
	done
	IFS="${OIFS}"

$1 will have the first field, $2 will have the second, $3, the
third.. no quotes, but you'll need to remember to quote the
variable as you pass them around and manipulate them.
