MC, You are not far from the basic premise of what you are trying to do... 1. To get your loop to run for more than 1 iteration right-click on the boolean (wired to the stop indicator) and select "change to control". Now when you run the program the loop will iterate until the control is pressed to True. 2. Instead of casing out the data value itself, I would recommned incorporating the file write operation into the case structure. This way the file will only be written when the boolean is ON (True). This should get you started. 3. Might I also suggest adding a small loop delay to control how fast your loop iterates (slow it down to allow your PC to handle other processes). Hope this helps... ES
