The quest for a "better" VLX decompiler is the Holy Grail for AutoCAD developers who have lost their source code or are trying to understand legacy routines. Because VLX files are compiled LISP (FAS) containers, they are intentionally designed to be a "black box."

Case 2: Security Audit

You suspect a third-party VLX is sending drawing data to an external server (malware). A superior decompiler exposes all (vlax-invoke ... "getRemote") calls and HTTP (vl-file-copy) to FTP paths. A poor tool misses these because it fails on the obfuscated network routines. vlx decompiler better

If you are interested in the theory of how decompilers are being improved generally (which can be applied to LISP structures), recent research includes: The quest for a "better" VLX decompiler is

Case 1: The Ghost Developer
