Wenn Sie bereits mit frühen Versionen von Gamestudio gearbeitet haben, erinnern Sie sich wahrscheinlich noch an einen anderen Namen für die Programmiersprache: WDL. In der derzeitigen Version wird WDL lediglich für Projekteinstellungen benutzt und die alten BASIC-ähnlichen, WDL-spezifischen Strukturen und Befehle sind in diesem Handbuch nicht mehr dokumentiert und sollten in neuen Skripten nicht verwendet werden. Im Folgenden sind sämtliche überholten Anweisungen und Schlüsselworte zusammen mit der Engine-Version mit der sie verschwunden sind, aufgelistet:
