   $ARGUMENTS$
      <cSearch> is the character substring to search for.

      <cTarget> is the character string to search.

      <nOccurs> is the occurrence of cSearch to look for,
                 defaults to 1.

      <lCaseSens> is a logical value denoting case sensitivity.
                 If .F., then search is NOT sensitive to case,
                 defaults to .T.
   $RETURNS$
      The position of the nth occurrence of a substring
   $DESCRIPTION$
      This function will find the nth occurrence of a substring
      within a string.
   $EXAMPLES$
      cSearch := "t"
      cTarget := "This is the day that the Lord has made."

      ? ft_At2( cSearch, cTarget )            // Returns 9
