> Any ideas how to identify potential unintentional loops? That depends on your design. Is it intended that the 3 procedures can call each other, directly or indirectly? If no, then things are a lot easier. You can just put on the currently entered procedure name to a map shared by the 3 (or just make it global) and on start of each procedure, you check whether the current procedure is in the map already or not. If yes, then the current call stack has formed a recursion.
