2nd Edition. This is the text of the second edition, published in 1992,
out of print in 1997. Much of the material was also included in the 1st edition, which was
published in 1980. Updates will be made to this online edition as I get the time to do it.
The current version was reorganized nicely by Larry Widing (lwiding@netg.com.) Any questions on the content,
you can get in touch with me at jfdunnigan@verizon.net.
