- This directory ([.SYS.VMS]) contains the VMS-specific files for MG.
-
- +-----------------------+
- | Construction |
- +-----------------------+
-
- By this point you should have put the ``system-independent'' files
- into a directory of your choice, then put the VMS files into the
- subdirectory [.SYS.VMS]. You should also put the termcap terminal
- driver into the subdirectory [.SYS.DEFAULT], and the termcap library
- files into [.SYS.TERMLIB]. These come with the standard MG distribution,
- so you shouldn't have much trouble.
-
- The command file MAKE.COM is designed to compile and link the entire
- program, using the VMS system functions and the termcap terminal
- driver.
-
- To invoke MAKE.COM, enter
-
- SET DEF dev:[emacs-dir] ! location of system-independent files
- @[.SYS.VMS]MAKE ! go have some coffee...
-
- This will create the termcap library, compile each of the necessary
- modules, and link the entire program into dev:[emacs-dir]MG.EXE.
-
- NOTE: To keep the size of the executable program down, MAKE.COM
- attempts to link in the VAX C shareable run-time library. Since VMS
- 4.4 and up have the VAX C run-time library bundled into it, there
- shouldn't be any problem finding it. If there is, modify MG.OPT to
- link with SYS$LIBRARY:VAXCRTL.OBJ/LIB instead.

- | Specifying Your Terminal With Termcap |
- +-------------------------------------------------------+
-
- (CAVEAT AND CREDITS: The termcap subroutine library in
- [.SYS.TERMLIB] was written by Fred Fish (of Amiga Public Domain
- Library fame) and placed in the public domain. It is not guaranteed to
- be a complete implementation of the Unix termcap(5) library; the usual
- disclaimers (like "it works for me":-) apply here. I have modified it
- to support the tc= capability, which lets you define terminals in
- terms (pardon the pun) of other terminals, so it should work
- reasonably well with the termcap provided in [.SYS.TERMLIB]TERMCAP.)
-
- To use the termcap library, you need to tell it where to find a
- terminal definition (termcap) file. If you have GNU Emacs installed,
- MG will use its termcap file from EMACS_LIBRARY:[ETC]TERMCAP.DAT.
- Otherwise, it will try to find the file which on Unix systems is
- called /etc/termcap. To emulate the same behavior on VMS, DEFINE/JOB
- the logical name ETC to point to a directory that contains a termcap
- file, with the name TERMCAP. (no extension). (The /JOB qualifier is
- needed when you run MG as a spawned supprocess.)
-
- DEFINE/JOB ETC dev:[dir]
-
- If your system has Eunice, there is a large termcap file already
- available via this exact mechanism, so you shouldn't need to define
- ETC at all. If you don't have Eunice, never fear; a termcap resides
- in the file [.SYS.TERMLIB]TERMCAP., so all you have to do is
-
- DEFINE ETC [emacs-directory.SYS.TERMLIB]
-
- to get started. You get the idea. Lastly, if your site uses the
- logical name ETC for another purpose, you can define the logical name
- TERMCAP to point to the MG termcap file. You must specify the path in
- Unix format, with the root being the disk drive the file resides on.
- For example, if the termcap file is in DUA0:[USER]TERMCAP., the
- command would be
-
- DEFINE TERMCAP "/dua0/user/termcap"
-
- The VAX C run-time library can translate this into the appropriate VMS
- file specification for you (a rather nice feature...).
-
- Once you've indicated where the termcap file is, you can tell MG what
- kind of terminal you're using by defining the logical name EMACS_TERM.
-
- DEFINE/JOB EMACS_TERM "termtype"
-
- where "termtype" is in lower case and matches an entry in the termcap
- file. (Alternatively, you can define the logical name TERM and MG will
- look there if EMACS_TERM is not defined. Again, GNU Emacs uses EMACS_TERM
- and Eunice uses TERM.)
-
- NOTE: One performance aspect of termcap files is that they are
- searched sequentially, so you may want to move the most frequently
- used terminals at your site to the beginning of the file to minimize
- startup overhead.
-
- +---------------------------------------+
- + TERMINAL INITIALIZATION FILE |
- +---------------------------------------+
-
- The termcap terminal driver allows you to initialize MG differently,
- depending on what kind of terminal you're using. See
- [.SYS.DEFAULT]README for more information.
-
- +---------------------------------------+
- | INVOKING MG |
- +---------------------------------------+
-
- First of all, remember to set up the logical names for the terminal
- type and termcap file. This can be done just once, in your LOGIN.COM file.
-
- Then, to just run MG in your current process,
- $ RUN [emacs-directory]MG
-
- Or you can define a symbol to run it with command line arguments:
- $ MG :== $dev:[emacs-directory]MG
- $ MG [file]
-
- +---------------------------------------+
- | MG As a Kept Fork |
- +---------------------------------------+
-
- You can use [.SYS.VMS]MG.COM to spawn a MicroEmacs subjob, which you
- can then attach to and pop out of as you please. Edit the line at the
- top of MG.COM that defines the path to the image MG.EXE, then define a
- global symbol called MG:
-
- $ MG :== @dev:[emacs-directory.SYS.VMS]MG
-
- You can then use MG to edit files:
-
- $ MG [file]
-
- When inside MG, use the command M-x suspend-emacs (bound to C-z by
- default) to suspend the MG process and attach your terminal to the
- process that spawned it. To re-attach to MG, just issue the MG command
- again:
-
- $ MG [file]
-
- The command file will reattach you to your MG process, where you can
- continue editing where you left off. If you specify a new file to
- edit, the command file sets a logical name which MG then looks at when
- you reattach.

- | MG As a Mail Editor |
- +-------------------------------+
-
- As an added bonus, the file MGMAILEDIT.COM makes MG your mail editor
- when you use the SEND/EDIT command. Issue the command
-
- DEFINE/JOB MAIL$EDIT dev:[dir]MGMAILEDIT.COM
-
- to inform the mail system you want to use MGMAILEDIT.COM, then whenever
- you issue SEND/EDIT inside mail, MG will be used as your mail editor.
