Re: [Visualpython-users] Switch from vpython 3 to vpython 4

[Bruce S. <Bru...@nc...>]

I thought I remembered that import sys followed by sys.exit() would kill 
a VPython program. But when I try this on either Visual 3 or Visual 4 it 
doesn't have that effect. Does someone else know how to kiil a VPython 
program from the program?
