Description

The repeat structure without a number causes all the statements inside to execute in a loop until an exit, pass, return, or throw keyword is reached. The repeat structure with a number causes all the statements inside to execute in a loop with the specified number of iterations.

In OpenXION 1.3 and later, the statements under a lastly, then, or else keyword inside a repeat structure will be executed when the loop ends, unless the loop has ended because of an exit, pass, return, or throw.
