Understanding the AutoLISP Compatibility Analyzer (LCA)

The LCA enables you to check existing AutoLISP files to ensure that they work with AutoCAD 2000 drawings. Because of the many changes and enhancements made to AutoCAD 2000, numerous commands and variables were removed, replaced, or enhanced with additional properties. Consequently, before executing an AutoLISP routine that worked fine in previous versions of AutoCAD, you should use the LCA to confirm the routine performs as intended in AutoCAD 2000.

The LCA provides a dialog driven interface that enables you to identify the AutoLISP file(s) you want to check. After the file is identified, the LCA opens the AutoLISP routine and then steps through the code, line-by-line, checking each line of code for compatibility issues. If an issue is discovered, the LCA displays an explanation of the issue and enables you to make modifications. After you have finished checking the AutoLISP routine and have made any necessary modifications, the LCA saves the routine, and it is now ready to run properly in AutoCAD 2000.
