Turbo StartDelphi combines the user-friendlyness of Visual Basic with the precise control and speed of C++. Without lots of "real" programming, you can develop very efficient and fast Windows applications.
Delphi is a RAD tool, Rapid Application Development. It reduces the complicated task of programming Windows applications to the handling of "objects" in a visual environment.
Typing of source code is limited to a strict minimum. As a result, you can fully concentrate on what the program should do: this is top-down programming at its highest level, designing a nice Windows GUI interface becomes a breeze. You don't have to "program" any standard Windows elements, just a few mouse clicks and there's your fully functional listbox, file dialog box, or even a full fledged database grid.
With Delphi, debugging is limited to the program lines that you entered yourself, because all the ready-made modules that you use are tested and ready-to-go.
Compared to the limited possibilities of Visual Basic or the complexity of C++, Delphi is really refreshing. Once you've used Delphi, you'll be fascinated by its sheer development speed.
