The purpose of these files is to demonstrate how one could access 
the I/O page from Decus C. The example accesses a clock/calender
card and sets the system time. Since the clock data is read from
registers on the card a program must somehow access the I/O page
to get this data. By building these files and creating a device
partition, the I/O page can easily be accessed.
Prior to building the tasks, look at CLOCK.CMD and make sure you understand
what is going on. To build the set of programs, execute the indirect commmand
file CLOCK.CMD .
