arrays as subscripts [message #30805]

Hi All,

Suppose I have 3 arrays with the same dimensions: A, B and C.

I have to use the non zero elements of A as index to access B, then use
the accessed values from B as index to access C, and finally store the
values from C in a new array at the previously indexed positions of B.

Is there an effective way to do that in IDL? I can write a call to a
C function but I was wondering if I can do it only in IDL.

Any examples and help would be appreciated.

Thank you.

Lyubo
