Problem with the while loop stop !

[za3im_ensa]

I want to stop my while loop at any stage of execution without waiting for the subprogramme  exéxusion which is inside the loop.

I tried to use the concept of local variables as is shown in the attachments, but in vain

The while loop can only complete once everything in it has completed. If the loop contains a slow subVI, you need to find a way to query the stop condition inside the subVI.

As for the error you have to right click on the stop control and change the mechanical action to switching.
