Modifying the environment

[bosch@loria.crin.fr (Guido BOSCH)]

Hello,

I soon will start to build an own environment for a specification
language I have implemented with CENTAUR. Of course I will not start
from scratch but reuse a maximum of features from existing
environments (such as Metal, Ppml, Menumode etc.).  Because I did not
yet investigate a lot of effort to examine the corresponding sources,
here are some questions that you could probably answer in fewer time
than I would need to read the core manual or to examine the sources.

1.) In the "File" menu in a Centaur edit window I'd like to add a
    selection "Same File" to get rid of the anoying text window
    forcing me to re-type entirely the name of the file I want to
    re-read after some changes that I made on the original file
    (please dont tell me to use the "Edit" selection of the "Edit"
    menu -- I hate it ... ). How could I easily do this?

2.) I don't like the "Edit" window because its editing capabilities
    are much to restricted. Why not use a good existing exterior
    editor instead (Emacs, Epoch or emacsclient e.g.), as it can be
    done with many News and Mail handlers. So can you imagine an easy
    way how to call an exterior editor via a menu?

3.) What is the function that does the pretty printing of abstract
    syntax trees just as  plain ascii text. 


			Thanks in advance
