Easiest method to clear/zero an array of INT's RSLogix 5000

[tmadore]

What is the simplest method of clearing an array of integers in RSLogix 5000?
I could make a zero array of the same size and copy it, but that seems to take some time (approx. 400 INT array)

The FLL function would be great if it was able to fill arrays...

I am looking for some suggestions. Should I just stick with the synchronous copy?

FLL does fill arrays. The last instruction field is the number of elements to fill.

For multi-dimension arrays, use one for each dimension.

Why are you worrying about the time for a copy? Are you having performance problems or just anticipating them? Don't fix what isn't broken.

FLL does fill arrays.

That's correct!
I wrote a little code to test FLL statement vs a FOR-block, writing a 400 INT array, on RSEmulate. The results were 35uS (FLL) and 400uS (FOR block).

I stand corrected, Thanks for the help! it was the multiple dimensions that were throwing me off.
