First off, let me thank you very much for the massive amount of 
information you've given me thus far.  Do me a favor and tell me if 
this syntax is correct:

#!/bin/sh

. /etc/rc.conf

if [ "$grog_firewall_enable" = "YES" ]
then
         echo "Firewall enabled."
elif [ "$grog_firewall_enable" = "NO" ]
then
         echo "Firewall disabled."
fi

exit 0

This seems to work when I try it at a command line.  There's one other 
question. How would I add the following line (please correct syntax):

elif [ "$grog_firewall_enable" <> "YES" or "NO" ]
then
		echo "Syntax error in /etc/rc.conf file. grog_firewall_enable must be 
YES or NO"
fi


Thanks again for all the help.
