.ds
Dumps the protected-mode stack and displays near code-segment labels (if available) next to each doubleword value from the stack. One important distinction that should be made is the difference between the k and the .ds commands. The k command will walk the Windows stack as long as the debugger is stopped in Windows-based application or dynamic-link library (DLL) code. However, if the debugger is tracing through ring 0 code, the k command will not produce any useful output. For this reason, the .ds command has been provided to display the ring 0 stack.
