Until expression
Until marks the end of a Repeat/Until loop; the statements within are repeatedly executed until the expression is true.
The Exit keyword can be used to 'jump out' of the loop, continuing execution after the closing Until.
An alternative to Repeat/Until is Repeat/Forever, which repeatedly executes the statements within indefinitely.
