        *       Functions: This file contains
        *           my_fwrite

        *           tab_string

        *       Purpose: These functions write a string to a
        *                file.
        *
        *       Modifications:
        *           3 September 1986 - created from the routines
        *               in Jamsa's book on pp.  95-96.
        *           12 June 1987 - ported to Borland Turbo C and
        *               changed the names of functions from
        *               fwrite and fwriteln to my_fwrite and
        *               my_fwriteln. This is because Borland
        *               defines their own functions with the
        *               same names.

/*
 * NAME: my_fwrite (file_pointer, string)
 *
 * FUNCTION: Writes the string to the file specified by
 *           file_pointer insuring that a carriage
 *           return is not written.
 *
 * EXAMPLES fwrite (fp, last_name);
 *
 * VARIABLES USED: string: pointer to the string to be written.
 *                 file_pointer: pointer to the output file.
 *
 * PSEUDO CODE: while (the letter referenced by *string is not an
 *                     End of Line (EOL) or equal to NULL)
 *
 *                 write the letter to the file

/*
 * NAME: my_fwriteln (string)
 *
 * FUNCTION: Writes the string to the file referenced
 *           by file_pointer insuring that only one
 *           carriage is written.   If a line is read
 *           from a file, we have no way of knowing whether
 *           or not it contains a newline character.  If we
 *           assume it does, and none are present the output
 *           will consist of one long line.  If we assume it
 *           doesn't and it does, each line is double spaced.
 *
 * EXAMPLES fwriteln (file_pointer, address);
 *
 * VARIABLES USED: string: pointer to the string to be written.
 *                 file_pointer: pointer to the output file.
 *
 * PSEUDO CODE: while (letter referenced by *string is not an
 *                     End of Line (EOL) or  equal to NULL)
