When you begin debugging a program, you may not be able to identify which part of the code is introducing the incorrect behavior. To gain a better idea of how data progresses and changes as it flows through the code, you can use execution highlighting. Execution highlighting reduces the speed of execution and displays data bubbles that move along the wires, revealing the data that each node receives when it executes.

Execution highlighting helps you detect the following kinds of unintended behavior:
  • While Loops that never terminate
  • Case Structures that execute an unexpected case
  • Data values that do not match the expected value

You can turn on execution highlighting by clicking Highlight Execution on the Debug tab.
