Edit: (2016-08-03) In case anyone somehow ends up here in the future, you don't need to use user functions to get variable types, AutoIt has VarGetType() for that. However if you are looking for a function to show all variable details, you can use the following. #include-once ; #INDEX# ======================================================================================================================= ; Title .........: Variable ; AutoIt Version : 3.2.13.5+ ;
