Examining Suspended Program
A frame corresponds to an active method or function call. A frame stores the local variables of the called method or function, the arguments to it, and the code context that enables expression evaluation.
To examine frames of a suspended thread:
Select a thread from the thread selector drop-down list on top of the Frames pane.
Select a frame from the Frames list. The Variables pane shows all the variables available to the method call in this frame, so you can further explore them.
To navigate between frames, do one of the following:
Use up and down arrow buttons on the toolbar.
Use Up and Down shortcuts.
