Parameters
The Loop statement has the following parameters.
| Parameter | Description |
|---|---|
| statements | Any statements that follow Loop are initially executed, and then any While or Until test is evaluated to determine whether its value is true (non-zero) or false (zero). |
| test | An expression that equates to a Boolean value ¾ true (non-zero) or false (zero). |
| Until | If the Until format is used and the test evaluates to non-zero, the program control passes immediately out of the loop to the next statement after Repeat. But as long as the test evaluates to false, that is, until a certain specification has been met, the program will continue to loop. Loop While true.

Remarks
The Do following the Until and While statements is optional. You may use any number of Until and While tests in a single Loop...Repeat structure.
