TABLE OF CONTENTS Imagine somebody living in a two-dimensional black-and-white world with Spartan conditions in a rather crowded surroundings. There are only two interesting events: to start the program and to see that it has come to the finishing point. It is rather boring to live in such a world, isn't it so?
And now imagine, the wizard has transferred this somebody to a threedimensional color world. There is a lot of free space, he can breathe easily and it is possible to place many useful things here which can appear at hand when he needs them. All things around you are ready to serve you at your commands (or mouse clicks). In short, who wants to come back to the Spartan conditions of a two-dimensional world after tasting such a three-dimensional environment?
The programmer will feel similarly after transition from a two dimensional world with black-and-white-screen programming to a color world of Visual programming. In the latter you can open and write the information into any desirable window and store it there. At the necessary moment such a window appears above your other windows (in fact the world is quasi-three-dimensional!). The buttons await your click to produce a desired event. The head of a long column with numbers in a window is not lost; you can bring it back and do much more. I can say to some adherents of a command-line style, "OK, I see you can produce excellent C++ object-oriented code in a command-line...
