Modification History

  DMS, Dec, 1987.
  cloned from RDPIX by Marc W. Buie, March 1991.
  98/06/27, MWB, converted from !err to !mouse
  99/05/28, MWB, added kludge fix for operation on a Windows platform.
                  Unless RSI implements <return> (no line feed) this
                  routine (and rdpix) are not fully useful.
