99:  Where do I get Emacs that runs on VMS under DECwindows?

  Version 19.28 has a VMS directory containing installation instructions, a
  makefile, and various .com files.  But according to Richard Levitte
  <levitte@e.kth.se>, it does not run out of the box.  Even if it does, the
  VMSNOTES indicates that the Emacs on VMS is going to have much more
  limited functionality.  Richard Levitte has a patched 19.22 that
  supposedly has subprocess and networking functionality just as on Unix,
  with virtually the same lisp interface.  The source is available at

    ftp://ftp.vms.stacken.kth.se/GNU-VMS/Beta/EMACS-19_22-********.TAR-GZ

  where ******** is the release date of the kit.  For more information, see
