REBOL [ Title: "Get Patent" Date: 25-Nov-2001/19:11-5:00 Version: 1.2.0 File: %patent.r Author: "Bob Paddock and Astrid Sindle" 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. - %bpaddock--csonline--net The program is also example of how to use Rebol's: request-download choice[] ProgressBars/Time Estimates How to change face text on button press, and how to dynamically enable/disable a button. Real world application of Events. } Email: %bpaddock--csonline--net Web: http:///www.csonline.net/bpaddock library: [ level: none platform: none type: 'tutorial domain: none tested-under: none support: none license: none see-also: none ] ] GetPatent: func [ { Request a Patent Number to download from the net.
