About Using DCL to Define Dialog Boxes (DCL)

You define dialog boxes by entering DCL descriptions in ASCII text files, much like writing AutoLISP code. DCL files have a .dcl extension. A single DCL file can contain the description of one or more dialog boxes, or it can contain only prototype tiles and subassemblies for use by other DCL files. A DCL file consists of the following three parts, which can appear in any order. Depending on your application, only one or more of these parts is required.
