str.charAt(0) ... gefällt mir besser...

<script language="javascript">
<!--//
function gener(form) {
	var str = sernr;
	var str.charAt(5);
	var str.charAt(12);
	var str.charAt(9);
	var str.charAt(13);
	var str.charAt(10);
	document.getElementByName("code1").innerHTML = res;
}
//-->
</script>

<form>
	<input type="text" name="sernr" size="14">
	<input type="submit" onClick="gener(this.form)" value="Umwandeln">
	<output type="output" name="code1">
</form>
