Crazy while loop?

[Halemani]

Hey guys.
I have attached my problem. The problem is that, I have some while loops(3) running inside a a while loop, which inturn have single while loops in them. .  Now, I can stop all  the  while loops except the outer most.
I have seen in debug mode, stop4 button is not evaluated at all. Why?

Hi Halemani,

The outer loop can first be stopped if all inner loops are ready.
Why do you need such complicate arrangement? Can you explain what you try to do?

What is the Mechanical Action for the Stop4 button?

Can you explain what you are trying to do?

Yeah sure.
I have three readings to make and display them on charts(for each) for each reading i make.
Now, I need to show all the readings at a time and want to give option of starting and stoping  each loop(inside).
So, after I have done displaying and want to finish it all, I press the stop4 button.
Here is the vi. This is not the actual VI. The picture vi. Enjoy!

I don't have LV installed, so I can't look at your code, but why don't you use an Event Structure that allows the operator to select which readings to take and refresh the corresponding graph.  One single loop is all you need.

Mechanical action? I tried all. In vain!

Hi Halemani,

if you press the "stop4" button all other loops are still running, So you have to stop them once again.

But will that work for all the three operations I have mentioned? Because if you get inside one loop. Then you have to stop it to start others.

No I did not get you! My problem is that only. How do you stop the outer most loop?

Of course it will work.  The stop button then becomes a Stop Program button.  You can do one, two, three operatins, repeat them, etc until you press the stop (program) button.  You'd have 1 stop button and as many operations button as you need (three in this case).  And 1 single loop that is easily controlled.

The Event Structure is quite easy to implement.  And much cleaner solution.
