*
*  Description: The jstrchr function locates the first occurrence of "c" in
*               the KANJI string pointed to by "s". Jstrchr function starts to
*               search out from the top of string , and jstrrchr function starts
*               to search out from the end of string. This function is
*               a data independent form that accept far pointer argunments.
*               It is most useful in mix memory model applications.
*
*  Returns:     This function returns a pointer to the located letter, or NULL
*               if the letter does not occur in the string.
