*  Name:        _fjstrcmp               文字列を比較する
*
*  Synopsis:    x = _fjstrcmp( a, b );
*
*               int x;          結果
*               FJSTRING a, b;  文字列
*
*  Description: ２つの文字列を比較する。＿ｆｊｓｔｒｎｃｍｐは先頭から
*               ｎ文字分のみの比較をする。
*               ＡＮＫ文字　＜　カナ文字　＜　漢字文字　の大小関係に
*               になっている。
*
*  Returns:     文字列ａの方がｂよりも小さい場合は負数を、大きい場合
*               は正数を返し、ａとｂが等しいときは０を返す。

*  Name:        _fjstrcmp       compare strings with mixed KANJI letters
*
*  Synopsis:    x = _fjstrcmp( a, b );
*
*               int x;          resault as compared
*               FJSTRING a,b;   two strings for compare each other
*
*  Description: The _fjstrcmp function compares the KANJI string pointed to by
*               "a" to the string pointed to by "b". The _fjstrncmp function
*               compares only N number letters from top of strings.
*               The rule of comparison is as below.
*                 ASCII and numeric letter < KATAKANA letter < KANJI letter
*               This function is a data independent form that accept far
*               pointer argunments. It is most useful in mix memory model
*               applications.
*
*  Returns:     The _fjstrcmp function returns an integer less than, equal to,
*               or greater than zero, indicating that the string pointed to
*               by "a" is less than, equal to, or greater than the string
*               pointed to by "b".
