<title>break and continue</title>
<h>break and continue</h>
<part>
<text>The keywords <code>break</code> and <code>continue</code> are used for finer control of loops:</text>
<text>
<ul>
<li id="break"><code>break</code> ends the enclosing loop. Execution is continued after the end of the loop.</li>
<li id="continue"><code>continue</code> ends the current loop execution and continues with the next loop item from the beginning of the loop.</li>
</ul>
</text>
<h>Example:</h>
<code>for(var i = 0; i < 10; i++)
{
<funclink>Log</funclink>("Number: %d", i);
if(i > 6) break;
if(i > 2) continue;
Log("Number: %d (2. Ausgabe)", i);
}
Log("Final Number: %d",i);</code>
<h>Output:</h>
<code>Number: 0
Number: 0 (2.Ausgabe)
Number: 1
Number: 1 (2.Ausgabe)
Number: 2
Number: 2 (2.Ausgabe)
Number: 3
Number: 4
Number: 5
Number: 6
Number: 7
Final Number: 7</code>
<text>This loops counts the variable <code>i</code> from 0 to 10.</text>
<text>If the first three loop executions (i from 0 to 2) the value is displayed twice.</text>
<text>From value 3 on <code>continue</code> is called after the first output. This will skip the current loop execution. The output is made only once.</text>
<text>If value 7 is reached, <code>break</code> is called. <code>break</code> will, as opposed to <code>continue</code>, not only skip current loop execution but will break out of the whole loop. You can notice by seeing that the value of <code>i</code> is 7 at the end, not 11.</text>
