At long last I got my patent downloading script in a workable state. If
nothing else it will ack as example of how to do progress bars and downloads.

REBOL [
Title: "Get Patent"
Date: "Nov-21-2001 20:48"
File: %patent.r
Author: "Bob Paddock and Astrid Sindle"
Version: 1.0.7
Purpose: {
Downloads various types of patents from the l2.espacenet.com server.
Normally espace forces you to download the patents one page at a time.
This script gets all of the pages for you automatically.
Shows various progress bars and time estimates.
There may be patents that this does not get because I can not
find any documentation on how l2.espacenet encodes its URL's.
If you know how to encode a specific URL please let me know
so that I can add support for it. - [EMAIL PROTECTED]
