While and Do While Loops

Use the While Loop check box of the Loop operator to manage loop behavior. When checked, the Loop operator behaves as a while loop. When unchecked the Loop operator behaves as a do while loop.

Any existing Loop operators in content developed before an upgrade to CA Process Automation 4.0 will have the While Loop field unchecked. They will continue to behave as do while loops. You can turn these Loop operators into while loops by checking the associated While Loop box.

The two main differences between while and do while Loop operators are:

• While loops check the loop condition specified in the Repeat Count field before it executes the first iteration and each subsequent iteration.
• Do while loops check the loop condition specified in the Repeat Count field at the end of every iteration, so it is guaranteed to always execute at least the first iteration of the loop.

Note: A Loop operator can be set to behave as a while or do while loop. The other operators that support looping can only behave as do while loops.
