| Syntax | Repeat statements [Exit Repeat] [Continue Repeat] Until TestExpression |
| Action | [Statement] The enclosed statements continually repeat until TestExpression becomes True. |
| Scope | Usable anywhere. |
| Notes | The statements execute and TestExpression is evaluated. If TestExpression is True then control returns to the first line after the Repeat statement. Exit Repeat passes control to the next statement after the Until statement. Continue Repeat causes control to return directly to the first line after the Repeat statement. You may nest Repeat to as many levels as required. Note that the Repeat statement is similar to While, except that TestExpression is tested at the end of the structure, not the beginning. Thus execution of the enclosed statements occurs at least once. |
