AutoLISP includes functions for controlling the AutoCAD display in both text and graphics windows. Some functions prompt for, or depend on, input from the AutoCAD user.
The prompt, princ, prin1, and print functions are the primary text output functions. These functions were described in the AutoLISP Basics chapter, under the heading, Basic Output Functions
See Display Control Functions in AutoLISP Function Synopsis for a complete list of display control functions.
