(2) EXIT syntax
[Format]
EXIT;
[Explanation]
The EXIT syntax can be used in the repeat statement of an ST program
and terminates a repeat loop midway.
When the EXIT syntax is reached during execution of a repeat loop, the
repeat loop processing after the EXIT syntax is not executed. The program
is continued on the line that follows the one where the repeat loop
processing has been terminated.
