Does anyone know anyone that is familiar with both LISP programing for AutoCAD as well as DraftSight? We need someone to review our LISP programs that don't work correctly in DraftSight and give us a quote to fix these programs, if they can be fixed..

We have about 60 LISP programs that were developed about 25 years ago for AutoCAD that we maintain. We are currently looking at DraftSight Enterprise to replace AutoCAD. About a dozen of these programs do not function correctly in DraftSight. We have sent the problem LISP files to our VAR and they have not been much help. The VAR has now referred us to a consultant that is familiar with AutoCAD that may be able to rewrite the programs in Visual Basic since he is not familiar with LISP. 

We no longer have anyone in our company that is proficient in LISP, so we general contact out to an AutoCAD VAR when upgrading to newer version of AutoCAD if we have LISP program issues. We are assuming the reason that these LISP programs are not running correctly is because DraftSight’s interpreter is not a complete direct LISP interpreter.
