Visual languages overcome many of the drawbacks and limitations of the textual languages that software development is based on today. Do you think about programming in a linear fashion? Or do you draw a mental picture of your algorithm and then linearize it for the benefit of your compiler? Wouldn't it be nice if you could code the same way you think?
Visual C++ and Visual BASIC aren't visual languages, but Prograph is. Prograph is a commercially available, visual, object-oriented, data-flow language. It is well suited to graphical user interface development, but is as powerful for general-purpose programming as any textual language.
The talk will comprise a discussion of the problems of textual languages that visual languages solve, a live demonstration of Prograph, and some of my observations of the applications of Prograph to software development.
