How the HP ALLBASE/4GL Developer Works The HP ALLBASE/4GL developer provides you with application development facilities that can be grouped under the following headings: * Dictionary. * Screen development. * Logic. * Reports. You will work with each of these facilities in developing the sample application. The developer application uses menus and screens to guide you through each phase of the development process. You specify most application items by filling in formatted screens to define the details of the item. As you develop an application, your definitions are stored in a set of internal files. The application definitions exist in two forms: application "source" and the "generated" application. Conceptually, the source application is similar to source code and the generated application is similar to object code in a conventional programming system. The generated form is an executable form of the application. HP ALLBASE/4GL uses the instructions in the generated application to present the application items to the user. The application source code does not need to be present at run-time, although its presence makes no difference. The developer environment contains all the logic necessary to convert your application source code to the generated form. You don't need any external compilers or utilities. Both the developer system and the run-time environment contain all the necessary facilities to run generated applications.
