Scope

This specification covers:

• core AutoLISP syntax and evaluation,
• Visual LISP language extensions,
• host-visible runtime types,
• CAD interaction surfaces that are language-defining in practice,
• version and vendor divergence that must be tracked by clautolisp.

This specification does not attempt to reproduce full external standards for:

• DXF object schemas,
• COM type libraries,
• .NET, ObjectARX, or BRX APIs,
• every interactive CAD command.
