[PD] how to detect if array has changed

[Jack]

Just output the value store in the array at the desire index (with
[tabread]) before to write the new value (at the same index) and compare
this new value with the old with [==]. If the result is false (0) then
the array change. You get also the index that changed.
Or i miss something ?
