Was willst Du erreichen? Bzw. was erwartest Du, soll an die Funktion processResponse übergeben werden?
an processResponse() soll der Wert von kekser weitergegeben werden.
Ich will halt, dass wenn sich xmlHttp.onreadystatechange ändert, die function processresponse() aufruft...und dabei dann der wert von kekser übergeben wird, sodass kekser dann in der processdata() an document.getElementById() übergeben wird und dann der Inhalt,am Tag mit der Id=(hier:lesen), durch AJAX ersetzt wird.
gesamter code:

var xmlHttp = false;

// constants
