# break

## Purpose

Break out of flow control structures.

## Synopsis

    break

## Description

`break` terminates the execution of `for` and `while` loops. In nested loops, `break` exits from the innermost loop only.

## Examples

The indented statements execute until the user enters a nonpositive `n`.

    while 1
        n = input('Enter n. n <= 0 quits. n = ')
        if n <= 0,break,end
        r = rank(magic(n))
    end
    disp('That''s all.')
