Evaluating a nexted variable

[Doug McNeil]

Hello,

A friend needed to get the value of a variable which was contained in
a variable:

$a=b
$c=a

Determing the value of "a" given "c".

I came up with:

$eval z="$`echo $c`"
$echo $z

Not being a shell guru, I expect there are lots of better ways to do
this. Any comments?
