For an object like AArray100, how may I specify reading and writing to index-parameterized selected elements in the Plc coding environment? The Mux object is cumbersome and only addresses 24 items total.

I wrote a 'hack' that works using CArithm - but I would feel more secure using a designated ProviewR method.
(Take the address in C of element 0, assign a pointer as an array and index it with an integer)

Hi Bruce,

You can use a DataArithm and fetch a pointer to the AArray with a GetData and connect to the Da1 input. The code would be something like
classdef Da1 AArray100;

for (i = 0; i < 100; i+)
  Da1->Value[i] = ...
