+** for the VOS STDGRAPH graphics kernel text i/o routines.  These are used to
+** do direct i/o to the graphics terminal, whether or not the terminal is in
+** graphics mode.  When the terminal is not in graphics mode, i.e., when the
+** "workstation is deactivated", these routines are equivalent to the FIO
+** putline and getline procedures.
