Call Stack
The Call Stack window displays the nested method calls currently on the stack. Whenever a method is called, an entry is added to the call stack. When this method calls another method, another entry is added to the stack. When a method is completed, its entry is removed from the call stack. The current method is always displayed at the top of the call stack, and the method from where it was called is displayed directly below.
For more information, see Using the Call Stack Window.
Message
Displays the decorated name of the method (i.e., with the msg_, get_, or set_ prefix).
Object
Displays the name and object ID of the object in context for the specified method. The Object column is empty if it's a global procedure/function.
Switching Call Stack Frame and Method Context
To switch to another call stack frame, click the specified entry in the Call Stack window. Clicking a Call Stack entry takes you to the source code for the current line in that call stack frame, and the Local Variables window is updated with the local variables for that method context.
