break-loop will exit a loop between start-loop and end-loop, run-query and end-query, or read-line and end-read-line statements. Execution continues right after the end of the loop.
Examples
Exit the loop after 300 loops:
set-number max_loop = 300 start-loop repeat1000 use i start-with1 @Completed <<p-num i>> loops so far
if-true i equal max_loop
break-loop end-if end-loop
