About Peter

Gemtree Peter is a visual programming tool designed for a simple and fast generation of the programs for Windows 95/98/NT/ME/2000/XP/Vista. Its principal characteristic is the graphical presentation of the program structure. The program sections are assembled using the mouse like a jigsaw puzzle. Thanks to the justification check of the element combinations, carried out already at the time of the program generation, there is no chance of syntactic failure origination. The program presentation by means of a tree structure enables a considerable improvement of the program lucidity. The creation of the program is quickly becoming extraordinary easy and flexible.

Gemtree Peter is intended for a broad range of the users. By using it, even the children of the pre-school age are able to draw pictures and teach their little rabbit to move. On the other hand, there are a lot of powerful functions intended to use by skilled programmers. It is not Peter's goal to train programmers out of all users. Its objective is to make the program generation accesible to all who want to create. No knowledge in the programming or computer areas is necessary. Everything is covered by the numberless functions. This is an effective mean for training the logical thinking, imagination, and aesthetic feeling.

To run it, a 486 computer using Windows 95 or Windows NT 3.5 with 10 MB disk space is sufficient.

In future it is assumed just fix the mistakes that was created due to transformation Peter to freeware.
