Part VII invites you to go the distance and start programming AutoCAD with AutoLISP, Visual LISP, and Visual Basic for Applications (VBA). AutoLISP is a powerful programming language that lets you quickly create your own commands and routines that are tailored to your needs. Visual LISP adds an easy-touse interface to AutoLISP programming.

VBA is a programming language that is supported by many Windows applications. You can create programs and dialog boxes for AutoCAD with VBA. Using ActiveX, you can write programs that integrate AutoCAD with other applications.

Unfortunately, AutoCAD LT doesn't support either AutoLISP or VBA. Therefore, this entire part applies only to AutoCAD.
