:Read and display the contents of a circular file

This application reads and displays the contents of a circular file.  To
 convert a file from circular file format to normal format, type at the
 command line:

    CircFileRead inputfile > outputfile

 This application requires the files CircFile.c and CircFile.h.

Warning!  This is a sample program to assist in the integration of the
 XMP motion controller with your application.  It may not contain all
 of the logic and safety features that your application requires.
