IDL V5 and Pointers [message #9620]

I just started using pointers in IDL. Does anyone know how to get create a
pointer that points to an existing variable, without duplicating the
variable and without making it undefined?

For example:

x=findgen(1000,1000,1000) ; a big array
.
.
.
lots of code
.
.
.
.
ptr=ptr_new()
ptr=&x ; this syntax is derived from C and is not valid in IDL.
; Does anyone know how to do the equivalent in IDL?

Thanks,

Charles Martin
