Loops - Do Loop

What is a Do Loop?

A Do loop allows you to repeat an action under certain conditions.

Do While

A Do While loop will loop while a condition is True.

The condition can be checked either before or after the code inside of the loop executes.

Do Until

A Do Until loop will loop until a condition is True.

The condition can be checked either before or after the code inside of the loop executes.

Remarks

Keep in mind that infinite loops are possible with Do loops. If you check for a condition that you know will always return a True value, then the Loop will execute until the application shuts down.
