REBOL [ Title: "Digital PCS Phone Pager" Date: 12-Jun-2000 File: %pcspager.r Author: "Kevin McKinnon" Purpose: { Check e-mail account for messages, then process for paging to a Digital PCS phone. The processing includes chopping message/sender lengths and url-encoding. My cellular company wanted an extra $3/month just to give me an e-mail address that does what this script does. (Can you believe that? $3!) My PCS provider is Cantel AT&T in Canada. You'll need to modify the script to work with your PCS carrier if you're not on Cantel. } Comment: { Bits of this script have been aquired and modified from the REBOL website and from code fragments posted to the REBOL User Mailing List. Thanks to everyone who has contributed code! Logging directory per *nix standards. Tested under REBOL 2.0.4, and 2.1.0 } Email: %kev--insinc--ca library: [ level: 'intermediate platform: none type: none domain: 'other-net tested-under: none support: none license: none see-also: none ] ] comment { Define constants for easy customization } messagelength: 126 fromlength: 20 targetarea: 250 targetprefix: 442 targetnumber: 6111 pagerserver: tcp://sabre.cantelatt.com:80 pagerscript: "/cgi-bin/sendpcs.cgi" eol: "^M^J" comment { The url-encode function was appropriated from the REBOL website at www.rebol.com/library/urlencode.r The original author was uncredited.
