Hi! I installed the Alliance Software using the windows version. My computer is currently with the windows 2000 version. I followed the combinational example of a 1-bit fulladder in the documentation. How do I set the environmental variables using the windows command prompt? I have gone through the Asimut and it compiled without error. However, upon execution of the Genpat, it wasn't able to do so. It didn't recognize "genpat" as a command. What could possibly be wrong? Thank you very much! Hoping for your immediate reply. Wilmyna Descallar Science Research Specialist II Advanced Science and Technology Institute
