*  Name:        _fjstrcat               文字列を結合する
*               _fjstrncat
*
*  Synopsis:    p = _fjstrncat( to, from, n );
*               p = _fjstrcat( to, from );
*
*               FJSTRING p;     ｔｏと同じ値
*               FJSTRING to;    結合される文字列
*               FJSTRING from;  結合する文字列
*               int n;          文字数
*
*  Description: 文字列ｔｏの後に文字列ｆｒｏｍの先頭から
*               ｎ文字分だけ結合する。
*
*  Returns:     第１引数ｔｏと同じものを返す。

*  Name:        _fjstrcat                concatenate KANJI strings
*               _fjstrncat
*
*  Synopsis:    p = _fjstrncat( to, from, n );
*               p = _fjstrcat( to, from );
*
*               FJSTRING        p;      same value as argument "to"
*               FJSTRING        to;     distination KANJI string pointer.
*               FJSTRING        from;   KANJI string pointer for appendage
*               int             n;      number of letters should be appended
*
* Description:  The jstrcat and jstrncat functions append a copy of the KANJI
*               string pointed to by "from" to the end of the KANJI string
*               pointed to by "to".  The first letter of "from" overwrite the
*               null character at the end of "to", and jstrncat appends only
*               "n" number of letters. This function is a data independent
*               form that accept far pointer argunments. It is most useful
*               in mix memory model applications.
*
*  Returns:     The value of "to" is returned.
