Subject: storing and using references to variables

Hi,
   I want to store a reference to a scalar variable (in perl parlance) 
in another variable and then assign a value to the stored variable.  I 
have done this for contiainers by simply assigning the container to the 
variable:

 ref = a = []

ref[0] = 'x'

leaves a[0] == 'x'

as it should.

I want to be able to do something similar but using a simple variable 
instead of an array. E.g. in perl

$ref = \$a

$$ref = 'x'

but I can not find anything about explicitly dereferencing a variable.

what I have done in the mean time is to use an array and only use the 
first element.

Cheers, Russell
