Nope, I meant "file".  In an INPUT tag, the name= attribute defines the
name in the form.  In my last posting, I called the field "file".

<FORM METHOD=GET ACTION="/cgi-bin/form.cgi">
First name: <INPUT name="first" type="text"><BR>
Last name: <INPUT name="last" type="text"><BR>
</FORM>

Give a URL of "/cgi-bin/form.cgi?first=Sharriff&last=Aina".

And for a file upload:
<FORM METHOD=POST ENCTYPE="multipart/form-data"
  ACTION="/cgi-bin/form.cgi">
Filename: <INPUT name="uploadfile" type="file"><BR>
</FORM>

gives:
--192168202199
Content-disposition: form-data; name="uploadfile"; filename="menu.txt"

Spam, spam, eggs & toast
Spam, eggs, toast and spam
Spam, spam, spam and spam
--192168202199--

Here you would get:
>>> form['uploadfile'].filename
'menu'
>>>

The name is "uploadfile".
