Not exactly. I've AmigaIzed XLISP 2.0, with the following points:
1) ability to call ANY libraries that can be specified by a fd.file
(that is arguments are passed in registers, not on the stack)
2) manipulation of C structures form XLISP, using the OO features.
this uses a modified form of include files.


All this needs only a tiny object module that provides a new function
I called callasm, and also some functions to read/write directly memory
at a given address, bye/word/long at a time.
Besides this object module, EVERYTHING is written in XLISP. yes.

Now, what's my problem: I have the permission of Carolyn Scheppner to
distribute my modified include files needed for manipulating C structures.
BUT, David Betz requires that people willing to distribute a non-standard
version of XLISP ask him for permission. I send Mr Betz a disk with 
my implementation on it monthes ago, and I've had no answer.

I think I will send to Fred Fish the only parts needed to AmigaIze XLISP2.0,
together will the lisp code and include files as soon as possible.
If one of you has the possibility to reach Mr Betz, I would appreciate
his/her help
