Visual Fortran gives you an easy way to create simple dialog boxes that can be used for data entry and application control. Dialogs are a user-friendly way to get and process input. As your application executes, you can make a dialog box appear on the screen and the user can click on a button or scroll bar to enter data or choose what happens next. You can add dialog boxes to any Fortran application, including Fortran Windows, Fortran QuickWin, and Fortran Console applications.
You design your dialog with the Resource Editor, and drive them with a combination of the dialog routines, such as DLGSET, and your own subroutines. A complete discussion of how to design and use dialog boxes is given in Using Dialogs.
