     These are some preliminary programs that came out  of  our  first  six
     months with V4 of VAX/VMS.

     1.  BREAK Terminals which are set to be /DISCONNECTable  can  generate
         lots  of  spurious  jobs  if users lean on the BREAK key too much.
         Since our users were used to pounding on the BREAK key to talk  to
         a  IDX3000,  V4  VAX  systems  often  had 64 detached jobs running
         LOGINOUT.  BREAK is a detached program (may be  easily  integrated
         into  your  existing DAEMON) which detects these monsters and cuts
         them off (before the normal disconnect process timeout)

     2.  ED1  When  Digital  gave  us  callable  EDT,  we  implemented  the
         long-requested       EDT-which-remembers-the-last-file-you-edited.
         GOODBYE to all those awful EDT.COM files FOREVER!  Also,  for  the
         fun  of it, I implemented XLATE functionality, which allows you to
         go directly from EDT into PHONE, MAIL, or DCL and then  back.   It
         was  easy.  See our example EDTINI.SYS file for information on how
         to include this functionality.

              This particular program also implements file  locking;   that
         is,  no  two people can edit the same file at the same time.  This
         was done for a particular customer;  you may wish to  comment  out
         calls  to ED1$ACQUIREMUTEX and ED1$RELEASEMUTEX if this feature is
         not needed at your site.   In  that  case,  you  may  also  ignore
         ED1MUTEX.MAR.   (I'm  not  sure,  but since it uses $ENQ, it might
         even work on a cluster???)

     3.  ARRAYEDIT While writing ED1, I  also  thought  that  a  subroutine
         which  edits a FORTRAN character array might be handy, and here it
         is.  Read ARRAYEDIT.FOR for documentation.
