Hi,

I'd appreciate any answers you may have to the following simple(?) question. It 
concerns variable substitution in a C-Shell:

Suppose I have:
@ num = 5
set str = num
alias ech 'echo $\!*'

So:
(ech str) will output num, but (ech $str) won't output 5. The error message 
says: variable syntax.

In other words:
$str = num, but how may I do something like $($str) ?


Thanks in advance.
