Purpose


  Gets IDL variable from a different IDL call level

Calling Sequence


  RESULT = DXGET('NAME') ; quoted variable name (OR)
  RESULT = DXGET(NAME) ; unquoted variable name

Description



  DXGET retrieves a variable value from any point in the IDL call
  stack. The DXGET and DXSET routines allow any variable at any
  level to be examined and changed.
  The call level to be examined is determined by the current
  debugging "focus." By default this is the deepest level in the
  call stack -- where the breakpoint occurred. However, this level
  can be changed by using the DXUP and DXDOWN procedures.
  If the variable doesn't exist, then an error message is reported.

Inputs



  NAME - the name of the variable, either quoted or unquoted.

Keywords



  LEVEL - the call level to be examined, if not the current
          debugging focus.

Example



  value = dxget('a')
  Retrieve the value of the variable A from the debugged call level.
