 remove()                Delete A File

 #include   <io.h>                       Required for declarations only
 #include   <stdio.h>                    Use stdio.h for ANSI compatibility

 int        remove(pathname);
 const char *pathname;                   Path name of file to be removed

    remove() deletes the file designated by 'pathname'.

    Returns:    Zero if the file is successfully deleted.  On error, -1
                is returned and 'errno' (defined in <stdlib.h>) is set
                to:

                    EACCES      'pathname' is a directory or read only
                                file; or
                    ENOENT      file name or path name not found.

           {
                 int rslt;

                 if ((rslt = remove("c:\auto\invoice.dat")) == 0)
