Purpose


  Move the debugging focus deeper down the IDL call stack

Calling Sequence


  DXDOWN [ , NLEVELS ]

Description



  DXDOWN moves the debugging "focus" deeper down the IDL call stack.
  By using this procedure and DXUP, one can navigate up and down an
  existing call stack, and examine and set variables at various
  levels.
  While IDL always keeps the command line at the deepest call level
  (i.e., where the breakpoint occurred), DXDOWN and its related
  debugging procedures maintain a separate notion of which part of
  the call stack they are examining -- the debugging "focus."
  DXDOWN moves the debugging focus deeper by at least one level, but
  never beyond the deepest level.

Inputs



  NLEVELS - option number of levels to move. Default (and minimum)
            value is 1.

Example



  dxdown
  Move the debugging focus down one level.
