PYTHONPATH & Win 98 - seems broken

[Mitchell Timin]

Admittedly, I'm a newbie, but it seems clear enough that the PYTHONPATH
variable should let me access a .py file in a different directory.  details:

I'm working in a DOS window.  PYTHONPATH is set to:
c:\"my documents"\python.  In that directory is a file prog.py.  My current
directory is c:\Python16.  I type: python prog.py, and I get the message
"can't open file 'prog.py'.

?

Thanks in advance,
