This documentation and the accompanying software, including all of the example C programs and text files, are 
protected under United States copyright law to protect them from unauthorized commercialization. This entire 
tutorial is distributed under the "Freeware" concept which means that you are not required to pay for it. You are 
permitted to copy the disks in their entirety and pass them on to a friend or aquaintance. In fact, you are 
encouraged to do so. You are permitted to charge a small fee to cover the mechanical costs of duplication, but the 
software itself must be distributed free of charge, and in its entirety. 

If you find the tutorial and the accompanying example programs useful, you may, if you desire, pay a small fee to 
the author to help compensate him for his time and expense in writing it. A payment of $10.00 is suggested as 
reasonable and sufficient. If you don't feel the tutorial was worth this amount, please do not make any payment, 
but feel free to send in the questionnaire anyway. 

Whether or not you send any payment, feel free to write to Coronado Enterprises and ask for the latest list of 
available tutorials and a list of the known Public Domain libraries that can supply you with this software for the 
price of copying. Please enclose a self addressed stamped envelope, business size preferred, for a copy of the 
latest information. See the accompanying "READ.ME" file on the disk for more information. 

I have no facilities for telephone support of this tutorial and have no plans to institute such. If you find any 
problems, or if you have any suggestions, please write to me at the address below.
