I have added "cut-n-paste" to the x3270 program.
It has only been tested with Sun Openwindows 2.0...

The default keymap has also been changed to the
Sun-4 keyboard.

Because the cut-n-paste.c contains code fragments
from the MIT X11 tape, the MIT X11 copyright applies.

So far, this version has been tested with the following
combination:
  1) Sun workstation, SunOS 4.1, Openwindows 2.0,
     X11 and Xt libraries, the xnews server.
