To end a debugging session and exit the debugger, choose Exit Debug?
  from the File menu on the main window.  This invokes a Confirm Exit
  dialog box to verify that you wish to exit the debugger.  In the kept
  debugger, clicking on Yes returns control to system level.  In
  client-server mode, allows you to exit the client, the server, or both.

  To rerun your program from the current debugging session, see the
  Rerunning the Same Program topic.

  To run another program from the current debugging session, see the
  Bringing a Program Under Debugger Control topic.
