I'm looking for a way to reference a variable in the Bourne-shell,
whose name is given in another variable.  I found the following solution
using a sub-shell myself, but it seems rather clumsy:.

export x1; x1=one
export x2; x2=two
echo which var\?
read xx
sh -c "echo \$x`echo $xx`"

Are there any better/faster/shorter ways?  Perhaps using "eval", but
also executes the string, which is too much.
