is a graphic programming tool for the

operating system. Programs can be built by the

graphic assembly of blocks which represent pieces of program code. Win+Drive is especially useful for
designing the software of control systems. It generates C code that can be compiled and run on different target
platfurms including the PC itself.

Complex projects get soon so complex that it is not possible or useful to have all blocks in one schematic. For
splitting a project into several schematics compound blocks are provided. Compound blocks contain basic
blocks and other compound blocks. Compound blocks are inserted into schematics similar to basic blocks.
The inputs and outputs of compound blocks represent their connection to the upper level of hierarchy and
build the ports of inserted compound blocks.
