Using the AutoLISP Language
Using the AutoLISP Language
AutoLISP Expressions
You can use number, string, and list-handling functions to customize AutoCAD.
This chapter introduces the basic concepts of the AutoLISP® programming language. It describes the core components and data types used in AutoLISP, and presents examples of simple number-, string-, output-, and list-handling functions.
AutoLISP code does not need to be compiled, so you can enter the code at a Command line and immediately see the results. Some examples in this chapter are intended to be entered at the Visual LISP® (VLISP) Console window prompt (_$), while others are entered at the AutoCAD® Command prompt (Command:).
