FT_NOOCCUR()
 Find the number of times one string occurs in another

 Syntax

      FT_NOOCCUR( <cCheckFor>, <cCheckIn> ;
                  [, <lIgnoreCase> ] )      -> <nOccurrences>

 Arguments

     <cCheckFor> is the string to search for

     <cCheckIn> is the string to search

     <lIgnoreCase> is a boolean variable to force case sensitivity
     (optional, defaults to .F.).

 Returns

     The number of times <cCheckFor> appears in <cCheckIn>

 Description

     This function finds the number of times a string occurs in a
        second string.

 Examples

     // Find the number of times "the" appears in cMemoString, case
     // insensitive

     nNoOfOccurrences := FT_NOOCCUR( "the", cMemoString )

     // Find the number of times "the" appears in cMemoString, case
     // sensitive

     nNoOfOccurrences := FT_NOOCCUR( "the", cMemoString, TRUE )

FT_AT2()
 Find position of the nth occurrence of a substring

 Syntax

      FT_AT2( <cSearch>, <cTarget> [, <nOccurs> [, <lCaseSens> ] ] ) -> nPos

 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 )

     FT_AT2( cSearch, cTarget, 2 )         // Returns ( 17 )

     FT_AT2( cSearch, cTarget, 2, .F. )    // Returns ( 9 )
