/************************************************************************
*
* Purpose: Program to demonstrate the 'stat' function.
* The program will show the modification and access times
* plus the size of a file.
*
* Author: M J Leslie
*
* Date: 01-Jun-95 MJL Minor bug fixed.
* 13-Apr-95 MJL Inital Release
*
* Notes: This function is only available to Unix systems. If you
* are on a DOS machine, this will not compile.
*
* Compile: Change the #define (below) to a suitable file name on your
* system. The file name is not passed on the command line
* as I did not want to complicate the example.
