Tip #28: The WhileLoop component lets you loop repeatedly until a condition is met. This component is new in v22.1.

When you execute StartLoop:

• The While port link is executed. This link is where you test the loop condition.
  • If the loop condition is met, execute a Break block and execution continues from the Completed port.
  • If the loop condition is not satisfied, execution continues from the Do port.
• The Do port link is executed. When the execution thread ends, execution continues from the While port.

The only way to exit the loop is to execute a Break block, so be sure there is always a Break. Project analysis checks for this condition as well.

The DoWhileLoop works the same as the WhileLoop except the Do link is executed before the While link.
