Marks the end of a Repeat/Until loop. See Repeat for details and examples.
Note that the Until keyword is also found as a modifier in For/Next loops; see For for further details.
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.
