The DataCAD Developer Network (DDN) is an online resource for information and support for DCAL® (DataCAD Applications Language) developers as well as anyone interested in creating fonts, toolbars, hatch patterns, or linetypes for use in DataCAD.
I have written a small "hello world" program and tutorial for DCAL for Delphi. I have tested it using the Datacad11 Test Drive, which is about to expire. When I can afford to purchase a license for a full version of Datacad so that I may continue development, I may release these items to the community.
