This is the code from the text

   "A Book on C," third edition,
   by Al Kelley and Ira Pohl,
   Benjamin/Cummings, Redwood City, CA, 1995

The code in the two subdirectories

   dos         and         unix

is the same, only the filenames themselves are different.
The filenames in the dos directory meet the 8 + 3 MS-DOS
restriction on filenames.  Some of the filenames are
longer in the unix directory.
