Petr

Gemtree Petr is a visual programming tool designed for easy and fast creation of programs for Windows 95/98/NT/ME/2000/XP/Vista. Its main characteristic is the graphical representation of the program structure. The parts of the program are put together like a jigsaw puzzle using the mouse. By checking the meaningfulness of the combinations of elements during the creation of the program, any possibility of syntax errors is eliminated. Expressing the program in a tree structure brings a radical increase in program clarity. Program creation becomes unprecedentedly easy, clear and flexible.

Gemtree Peter is intended for the widest range of users. Already preschool children draw pictures and teach their rabbit to walk. For experienced programmers, on the other hand, there is a large number of rich functions. Peter does not aim to turn all users into programmers. He tries to make programming accessible to everyone who wants to create. No programming or computer knowledge is required. Everything is provided with a wealth of features. It is an effective means of exercising logical thinking, imagination and aesthetic sense.
