I have used syntax transformers. If anyone interested I have put
an extra page about it:

I am not sure what you mean by this. Can you elaborate?

> 2. Did you implement a language level in DrScheme for
AutoLisp?

No. I do not know how to do that. I will check the help desk.

> 3. Did you need to interface with the AutoCAD graphics
engine at all?

No. No parts of AutoCAD was used. 

> 4. Do you use MysterX (COM) to connect to Excel?

Unfortunately not. I create a CVS file. The reason is that
there is no
MysterX in AutoCAD, and exactly the same program must run in
AutoCAD and in the simulation environment.

PLT Scheme

No. At the moment it is easier to find an AutoLISP
programmer than a 
Scheme programmer.

Best regards,
