1.DBG> SPAWN
      $ ATTACH JONES
      %DEBUG-I-RETURNED, control returned to process JONES
      DBG> ATTACH JONES_1
      $

      In this example, the series of commands creates a subprocess
      named
      JONES_1 from the debugger (currently running in the process
      JONES) and then attaches to that subprocess.

    2.DBG> ATTACH "Alpha One"
      $

      This example illustrates using quotation marks to enclose a
      process name that contains a space character.
