This section describes what is a loop 'break' statement in H language.

A loop "break" statement is a statement that terminates a loop early before it reaches end of the loop condition.

# if a given number is a prime number
x = 6789;

isPrime = $true;
i = 2;
$while i < x, (
   isPrime = x % i > 0;
   $if !isPrime, $break; # stop the loop
);

$if isPrime, write("x is a prime number.");
$else, write("x is not a prime number.");
