Using one-time-only events to trigger value changes

[WillB123]

Hello. I have experience with LabVIEW, but not much experience with event structures. Here is my situation:

Lets say I have an input, X, which comes from an external source. X is essentially random, from -100 to 100. My output will be Y, which will be generated by labview.  I want Y to have an initial value of 0. The first time that X becomes greater than 10, I want Y to change to 1, and stay 1 from now on, until the first time that X becomes greater than 20. The first time that X is greater than 20, I want Y to change to 2, and stay at 2 forever no matter what X is, until the program is terminated. 

Basically the program will constantly be sampling X, and when X reaches a certain threshold, it will change and hold the value of Y until the next threshold is reached. 

Any help is appreciated.

The event structure is not useful for this situation.  Sounds what you really need is an Action Engine.  I'll let Ben's nugget speak for itself.
