/* mcPj004E3.c */

/* Real World Application of fileReader.c continues */

/* From old days, here is a note of progress.

 *       mcPj004A.c  << Sample 10.04

 *       mcPj004B.c  << Example fscanf(), Screen access.

 *       mcPj004C.c  My first successful FileAccess.  One word only.

 *                     It seems for me a compiling set of libraries were crucial.

 *                     OR, in PC's C, I didn't need #include , and 

 *                     this could be the reason.

 *       mcPj004D.c  My second successful FileAccess.  One line only.

 *       mcPj004E.c  This one, my third successful FileAccess.  Whole text.

 */

/* Now, finally, this program works completely parallel with PC's 

 *    (Borland C) file access. 

 *    One thing I am getting clear is about NULL.   NULL means '0' (zero)

 *    and it is only applicable to the Pointer, not to Arrey nor Variable.  

 */

/* (2004-12-23)  One page of explanation fits about 23 lines or around.   

 *    So, this naration display is designed for about 23 lines each.     

 *    This is a combination of Text-read (printf()) on Screen, and 

 *    waiting a user's input (scanf()) as I did in PC C-codes.

 *    It works well.   Now it is working at exact 20 lines.

 *    In PC version, I used 'clrscr()' to clean up the page for the next 

 *    page, but I didn't see it.  I mean I don't see 'conio.h' here.
