How to Create and Load a Startup LISP Routine - AutoCAD Blog.
AutoLISP source code can also be stored in files with a .mnl extension. A Menu AutoLISP (MNL) file contains custom functions and commands that are required for the elements defined in a customization (CUIx) file. A MNL file is loaded automatically when it has the same name as a customization (CUIx) file that is loaded into the AutoCAD-based product.
AutoLISP is a dialect of the programming language Lisp built specifically for use with the full version of AutoCAD and its derivatives, which include AutoCAD Map 3D, AutoCAD Architecture and AutoCAD Mechanical. Neither the application programming interface (API) nor the interpreter to execute AutoLISP code are included in the AutoCAD LT product line.
We will write a number of AutoLISP routines during the course. Many of these routines will be useful building blocks for future AutoLISP work that you will want to do. Some of these programs will simply need to be typed in; for others you will need to create the steps yourself. Not only will we learn the commands of AutoLISP, we will learn to begin to think in AutoLISP, to debug our programs.
AutoLISP lets users and AutoCAD developers write macro programs and functions well suited for graphics applications. AutoLISP applications or routines can interact with AutoCAD in many ways. These routines can prompt the user for input, access built-in AutoCAD commands directly and modify or create objects in the drawing database. By creating AutoLISP routines you can use AutoCAD as a design.

Posted on January 26, 2015 by AutoCAD Tips I’ve simply updated the AutoLISP code for an earlier post from Alan Thompson that lets you select a Line, Arc, Polyline, Spline and make breaks at the user specified distances along the object.
AutoLISP is a dialect of the LISP programming language (LISt Processing). LISP is the oldest high-level programming language, second only to FORTRAN. LISP has been the language of choice for the artificial intelligence in robotics. It is built into AutoCAD.
