Scope : VIM-8.0.69  for VMS and OpenVMS (folder: VIM80)
        VIM-8.2.222 for VMS and OpenVMS (folder: VIM82)
===============================================================================
1) The VIM files here where originally published here ( http://polarhome.com )
   by Zoltan Arpadffy (Stockholm, Sweden)
   Note: http://polarhome.com (still exists but will usually be powered off starting 2022-01-03)

2) Zoltan's earlier work with "VIM on VMS" can be found here:
        http://ftp.vim.org/ftp/vim/vms/
	https://vimdoc.sourceforge.net/htmldoc/os_vms.html
        https://vim-jp.org/vimdoc-en/os_vms.html
        
3) File "vim-80-ia64.zip" provides VIM-8.0.69 for "OpenVMS on Itanium" (no C compiler is required)

4) File "vim-80-69-vms-src.zip" contains source code for building VIM-8.0.69 on
   "VMS on VAX", "OpenVMS on Alpha" or "OpenVMS on Itanium" but a C compiler is required

5) An idle VIM session eats up too much CPU time (IMHO) so I fixed the problem.
   see file: "os_vms.c"
   then search for "NSR" (my initials)

6) how to use my file:

   $unzip vim-80-69-vms-src.zip        ! creates sub-folder [.VIM80-69]
   $copy os_vms.c  [.VIM80-69.src]     ! copy my patched file (you must preserve case)
   $set def [.VIM80-69]                ! drop into subfolder
   $set def [.src]                     ! drop into subfolder
   $type Make_vms.mms                  ! view Zoltan's notes
   $type INSTALLvms.txt                ! view other notes
   -------------------------------------------
   use your favorite make tool
   -------------------------------------------
   Zoltan said to type this:
       $mms /descript=Make_vms.mms /ignore=warning
   But I has to do this:
       $mmk /descript=Make_vms.mms /ignore=warning

7) my short cut:
   I had previously installed vim80 via this file: vim-80-ia64.zip
   So after I recompiled the source code in step 5 above, I just copied the newly 
      generated vim.exe to the old location.
