This article was first published on The Transactor volume 4 issue 02 (January 1983) by Paul Higginbottom.

Paul Higginbottom can be found on his blog (higginbottom.com) and, since 2005 he has been creating websites and other media, and providing professional technology consulting to individuals, businesses and other organizations across the world through his company Reora, Inc.
