/* Sample program which uses the registration key system. This program's
* security code is 24805 - I would suggest that you change this value
* use in any programs you have written. When compiled, this program must
* be linked with the BP?.LIB file. For more information on compiling
* programs using the registration key system, please see the accompanying
* documentation, in the file REGKEY.DOC. This program reads the
* registration information from the file REGISTER.KEY. The program expects
* to find the registered user's name on the first line of this file, and
* the user's registration key on the second line of this file.
