Examining the Target Stack (backtrace, frame, up, down)

The target stack is made up of targets linked by a dependency from one target on the next. The debugger assigns numbers to target frames counting from zero for the innermost or currently executing target.

At any time the debugger identifies one target as the “selected” target. When the program being debugged stops, the debugger selects the innermost targets. The commands below can be used to select other targets in the target stack by number.
