  23 /*  FUNCTION
  24         Returns the name of the current default public screen. This will be
  25         "Workbench" if there is no default public screen.
  26
  27     INPUTS
  28         nameBuffer - A buffer of length MAXPUBSCREENNAME
  29
  30     RESULT
  31         None.
  32
  33     NOTES
  34         Only Public Screen Manager utilities want to use this function
  35         since it is easy to open a window on the default public screen
  36         without specifying a name.
