/* 2004-09-12 Note:  The Improvement in this 'Pro137.c'.
	  For convenience of Global Replacement (later at Linux),
	  to be Double Quoted all filenames in @fileNames (
	  Character String Array in PERL Header file 'scr37.ph'), all
	  filenames should have the same character at first and at end.
	  So, I decided to use DQ. (double quote) at first, and
	  .txt at the end.   Practically speaking, during import from
	  PC to Linux, all filenames are appended Asterisk (*), so
	  that, the end of filenames don't have to ajust.   I can
	  replace Asterisk (*) to Double Quote Comma(",).  Just I keep
	  the convention of .TXT as a text file in PC.                     */
/* As I am getting into 'Asterisk(*)' and 'Ampersand(&)' in C,
 *    I am gradually understanding that I should address more
 *    on MEMORY, location and value.  Then, I can write a gabage
 *    free C-programs.   Here is the combination from Dr. Aota's
 *    code of 'firstwd'.   This 'firstwd' routine doesn't look
 *    elegant, but works so well.
 */
/* I saw here that I can take care the directories PATHs
 *    at here too, such as \SDW\, \ZIP\,  and
 *    \SDW\Result\,  \ZIP\Result\.
 *    This 'Pro136C.exe' is going to revise to capture the
 *    user's desired Directory Path, and the automation at here
 *    is easier.  But I want a user to have an empty
 *    temporary working folder, for this reason, not too much
 *    automation, but a lot of comments like '1stBatch.bat'
 *    I did this morning are a good idea to make a user
 *    familiarize about this.  Especially, directory
 *    structure is the frame to review the results.
