On Win2k or XP, adding .py (for instance) to the PATHEXT variable means that you can execute "myNeatProgram.py" with this command-line: prompt>myNeatProgram Since .py appears in the PATHEXT variable, the system knows that .py files are executable, so it's not necessary even to specify them. What must happen, I suppose, is that the system looks for myNeatProgram.bat, myNeatProgram.com, myNeatProgram.exe, etc., until it hits upon myNeatProgram.py and proceeds to run it. So if you have a myNeatProgram.bat that appears earlier in your path than myNeatProgram.py does, the bat file is what gets run. -- rzed -- http://mail.python.org/mailman/listinfo/python-list
