Computer Programs:
This program. The program that you are running right now is
written in Turbo Prolog. It is a modification of a menu program
written to solve problems encountered with large systems that
required the inclusion of a variety of third party programs.

Accounts Receivable. I developed an accounts receivable program
for an oil and gas library. The problem was that no accounts
receivable program would handle the large number of transactions
and billing dues on a monthly, annual or semi-annual basis. This
was a contract for a computer dealer that sold a system and
couldn't find the software to make it do what he promised. This
was a very low budget job.


Salehandler a computer program for auctioneers that handles
bookkeeping, buyer registration, buyer pay out, seller settlement,
sales tax and more during the auction sale. It works on site in
real time. I developed the program and documentation. I have
marketed the program since 1978. I do the whole show. The program
has been moderately successful.

Copy protection. In the Salehandler program I designed and
implemented a method of copy protection that in the right
circumstances is 100% effective and completely benign to the user
as long as he doesn't want to steal the program. The method is to
encrypt his name and address in a file that is read by the
program. The special circumstance is that printed output must be
a major product of the program and the users customer, lenders or
clients must see the print out. The way it works is that in order
to be usable to the user it must have his name on it. The
benefits of this method are that demos can be freely distributed.
My experience, limited to the one program and a small sample, is
that over 50% of the demos result in sales. This could be
expanded to distributing a demo package at very low cost and
having the customer or dealer call in to a central and entering
the customer data and VISA Card number the central would send
back the encrypted file. The product would be registered, paid
for and distributed in one pass.

Embryo transplant accounting. This is a large system for a micro
computer. It consists of over 200 files and programs. It tracks the
ownership, calving, breeding, status and location of transplanted
and frozen cattle embryos. Also a 25,000 name mailing list is used
in conjunction with a program that tracks sales of registered brood
stock and handles the registration papers. This was a low budget
contract.

Oil well reporting. A program that uses input form a word
processor to file daily reports on several oil fields and file
them under individual wells. This system took a reporting section
of a national oil company from 6 months behind to two days behind
over a six month period. In the same time the staff that produced
the report was reduced by 50%. This was a contract job.

Front end for accounts receivable. Developed a system that takes
data from the key board and produces two streams of data one for
an existing accounts receivable program and the other for a data
base program. During development of this system serious problems
developed in the account receivable portion of the system. By
using the backup files produced by this system we were able to
reconstruct an entire month of transactions of a large farm
machinery dealer in four hours.

Computer magazine. In developing a menu program in Turbo PROLOG
it became obvious that a very similar program could be used to
produce a computer magazine. The result is the program that you
are now running. This same program with 30 minutes modification
can serve as a menu program, magazine, computerized documentation
or all three.

Writing:
Documentation for the Salehandler computer program. The original
was a conventional loose leaf binder. The latest version is a
computer file that is displayed and printed by a version of this
program. The advantage of this form of publication is that the
documentation can be kept in sync with the modifications of the
programs.

Magazine:
I write a monthly column for Country Magazine in Wichita Falls,
Texas. I am listed as a regional editor.

Well's Gulf Coast Fisherman has published several of my articles.
Other publication that have published my work include: The
Survivor, County Magazine, Science Newsletter, Discovery and
Science 86. I am a regular contributor of both photography and
articles to the Frederick Press and the Wichita Falls Record
News.
