Plus Equal in Labview?

[Spurbruenette]

Hi, 

I wonder if there is a Plus Equal Funktion in Labview like I can Programm in C?

"+=" works on variables. In LabVIEW you almost never need them. Think dataflow. Provide an example where you think you need "+=" and we can discuss that example.

Or for C programmers: Every operation in labview works like "+=" in C.

From this point of view, there is a lot missing in C 😋

Thanks for your help. The example is attached below.

The question and the answer:

Use a feedback node (or shift-register).

I changed the value of the constant in your example. If you want to us the constant to initialize the indexing, you can do it like described. Or just not connect it if it shall start at 0.

Increment (+1) is the closest i think.
