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 repeat 1000 use i start-with 1
@Completed <<print-out i>> loops so far
if-true i equal max_loop
break-loop
end-if
end-loop
