DCL File Format

AutoCAD Dialog Control Language Description file

The DCL file extension is primarily associated with an AutoCAD Dialog Control Language Description (DCL) file. AutoDesk's AutoCAD is a computer-aided design application. CAD software is used by architects, engineers, drafters, artists, and other design professionals to create precision drawings and technical illustrations.

A DCL file is a plain text file written in the AutoCAD's Dialogue Control Language (DCL) programming language. The file contains settings for dialog box elements such as buttons, title, text and so on. An application component  references the file and then displays the dialog box as specified for user input.

Other associations for the DCL file extension include Delphi component library files and DumpSec report files.
