Another useful debugging technique is to examine the flow of data in

the block diagram using the execution highlighting feature.

8. Begin execution highlighting by clicking on the Highlight Execution

button, in the toolbar. The Highlight Execution button changes to an

illuminated light bulb.

9. Click on the Run button to run the VI, and notice that execution

highlighting animates the VI block diagram execution. Moving

bubbles represent the flow of data through the VI. Also notice that data

values appear on the wires and display the values contained in the

wires at that time, as shown in the following block diagram, just as if

you had probed the wire.

You also can use the single stepping buttons if you want to walk

through the graphical code, one step at a time.

10. Begin single-stepping by clicking on the Step Over button, in the

toolbar.

11. Step into the Temp & Vol subVI by clicking on the Step Into button,

until the VI finishes executing.

12. Finish executing the block diagram by clicking on the Step Out button,

in the toolbar. Clicking on this button completes all remaining

sequences in the block diagram.
