TPUHELP.HLB  —  REFRESH
  REFRESH

     Repaints the whole screen, erasing any extraneous characters (such as
     those caused by noise on a communication line), and repositions the
     text so the screen represents the last known state of the editing
     context.

     REFRESH redraws each line of each window mapped to the screen.  The
     prompt area is erased.  The screen changes immediately:  even if
     REFRESH is done from within a procedure, TPU does not wait until the
     entire procedure is completed to execute REFRESH.

  Example

     The following procedure erases the message buffer and repaints the
     screen:

     PROCEDURE user_repaint
        ERASE (message_buffer);
        REFRESH;
     ENDPROCEDURE;
