This tool is of great value for programmers who want to document the use of symbols in their LISP code. To use, open the program using the VBAMan Command inside AutoCAD, then load it. Enable the macros and run the macro named "Start here." Select an input and output file, along with the options to be cross-referenced, and then select either the Document button (writes to file) or the View output with Notepad button. This tip includes example information and more explicit documentation with the download. If you are like most of us and have an extensive library of LISP code, this tool will help you keep it well documented. A tip of the hat from Harry for this extensive tip with loads of great examples that demonstrate how to do cool stuff inside VBA.
