system variables

[Daniel Powell]

hi guys,
I'm new to python and I'm teaching myself from a website. I'm stumped on one
thing this is the exact wording

"You will need to cause the directory containing the file named python.exe
to be listed in your system environment variable named path."
the website is
http://softwaredev.earthweb.com/sdopen/article/0,,12077_626311,00.html
it says when you do this if you type something like
"python junk.py" it will run the "junk.py" scipt
if anyone can help me do this i would grealty appreciate it.
My OS is Win 98SE

thanks in advance
Daniel Powell
