Expression for an empty array

[Riesengross]

Hello,

I want to reset an Array. Numeric 1D.

It's getting written on in my Sequence and when the sequence is ended I want to reset it as an empty Array. I want to do this through a statement. Can someone please send me the propper Expression I Need to use to make it empty again?

Hello Riesengross,

You can just set the number of elements in the array to 0, with this kind of statement:

Locals.MyArray.SetNumElements(0, 0x0)

Make sure your sequence is handling properly the empty array you've just reset.

Thanks, that worked.

Another easy way is, as I found out,

simply to write:

Locals.MyArray = {}

Simple assign Nothing like in SCALA.

Funny. "{}" seems to be interpreted as an "Array of Numbers(64-bit Floating Point)". Whenever you try to reset an array of a different type than that, it won't work. At least not in my Value expression that I'm trying to pass as a Parameter into a subsequence.

Static typing for the win!

So tell me NI, what's the literal for "empty array of containers"?
