*  Name:        _fjstrmatch     compute the initial position where searching

*
*  Synopsis:    p = _fjstrmatch( s, b );

*               FJSTRING        p;      pointer to the initial position of

*
*  Description: The jstrmatch function compute the initial position of the
*               string pointed to by s where occur the letters from the string
*               pointed to by b.  jstrskip function have the opposite
*               specification to jstrmatch, at the view of initial position
*               where not occur the searching letter. This function is
*               a data independent form that accept far pointer argunments.
*               It is most useful in mix memory model applications.
*
*  Returns:     This function will return the NULL pointer if it not occured
*               the letters from string pointed to by b.
