Paul,

I get the error:
Traceback (most recent call last):
   File 
"C:\Python23\lib\site-packages\Pythonwin\pywin\framework\scriptutils.py", 
line 310, in RunScript
     exec codeObject in __main__.__dict__
   File "C:\ShaRandom.py", line 50, in ?
     print test()
   File "C:\ShaRandom.py", line 47, in test
     s += v.random()
   File "C:\ShaRandom.py", line 14, in random
     return float(a)/newrand.m56
NameError: global name 'newrand' is not defined

Is this a problem with my Python installation or something defining 
newrand that you forgot to include?
