How to set a variable based on my current state, and default to tha variable if needed.

[Aaron_W]

I am working on a VI to control a robt car.

What I am trying to do is set a variable based on my current state.  For example I have 3 indicators, if the left one is active I want the varable set to a certain value, if the right is active I want the variable set to a different value.

The purpose is f all my indicators become inactive, I will have my vi default to the last state, which it gets from the variable t has been set.

Is there any way to do this is Lab View 2012.

You can store your state information in a shift register or use a functional global or DVR. If you want to have persistant storqage then you will need to write the data to a file.

Just to clarify the only state information I need stored is my current state, this way if I lose my state, and can default ack to my last knwn state.  Any other state prevous is irrelevant for my purposes.
