 *    while by using

 *    And tandem numbers of WHILE-loops becomes the field Number.
 *    Now, here comes the first prototype of Field Number Controlled
 *    given word Capture Recycable Object.
 *
 *    I tested this for Win3.1 "DIR.Txt" by 'Pro134E.prj', and works fine.

/* I wanted to make this one to be a geneic Based-on Field Number, Read and
 *    Write control.  Then it may be useful at various situations.
 *    By a quick test, this did exactly what I wanted.
 */
/* Now, at any given field, I can skip or make it blank.
 *     while () ++from;                ->  skip the field as if not exist.

/* By this "Field_No2.c" version, suppose No Details of output control
 *    is necessary, but just Field Number level control.
 *    Column position Counter "i" is deleted.
 *    -> Yes, this is working.  When I applied to Win3.1 "DIR.txt"
 *       It printed Field Shift in a few sporadic rows, since some of
 *       them don't have the 2nd Field "Extention" Word.
 */
/* This way is out of 'main.c', but rather Recycling Object Control.
 *    The 'main.c' can't control anything about.   I already have
 *    the 'Main.c' Control version by Column Position, so this would
 *    be the best complement to it.   Recycling Object like this is
 *    so tiny, and go anywhere, and so easy to read and modify.  Thus,
 *    in this point of view, also the best complement to 'Main.c'
 *    control.   So, use this conveniently.

/* This was originally, Liquid Paper on 4th Field.  Now, with
 *    'upField', 'downField' variables, Liquid Paper is moved into
 *    'main.c'.   Therefore, at here, I just need to,
 *        UpField    control     OR
 *        DownField  control
 * This one is for 'UpField' from 1st to 2nd.
 * Again here, I have Options for I do choose for mute-mode on 4th to end,
 * OR, do something else such 'break' to get out of While-loop.
 * Let me see.
 */
/* Actually this "fild_1up.c" doesn't have anything to do.  Because, 
 *    The 1st field is Actually Liquid Paper, then downField is 
 *    going to fill the rest.  But let me try in parallel as much.
 *    This is very stupid codes, since it's all mute-mode.  However, 
 *    it is good to see in parallel to the other options, so I 
 *    will test it if works.
