Yes, and there's no reason for $b$c to be expanded twice.  But 
it's easy to make it clearer:

	eval continent=\"\${$c}\"
	echo "$b$c) ${continent}" >&2

If portable /bin/sh is not feasible, then please use the 
intersection of ksh and bash syntax, and make it easy for the 
choice between ksh and bash to be made at install time.  (I have a 
minor preference for ksh over bash, because it's more likely to be 
available on non-linux systems, but if the choice is configurable 
then that's no big deal.)
