I have a set of GNU Emacs macros which emulate the TDS folding editor.
The macros were originally supplied by Inmos (with absolutely no support
implied).  Apparently the original was written by Tony Curtis of Exeter
University, and then subsequently modified by somebody named Erik. (I
don't know any more than this, I'm just attempting to give credit where
its due as best I can.)  I have modified the macros quite a bit myself
in an attempt to get them to more closely emulate the actions of TDS.

The macros are written in LISP and should therefore be portable to any
machine which can run GNU Emacs.  We're currently using it on Sun 3's, 
Sun 4's and Sparcstations.  The functions which are implemented in the
macros include: open/close fold, enter/exit fold, copy fold, move fold,
create/remove fold, and other "standard" editing operations (moving the
cursor around, deleting lines and words, etc.).  Note that filed folds
are not supported.  Also, in their current incarnation, the macros use
Emacs' point and mark extensively - something which in general should
be avoided and that experienced Emacs users may find to be a nuisance. 

If there is interest in the macro package I can either mail it to those
who are interested, or post it in comp.sys.transputer.
