   Cfts_Add( <CFTShandle>, <expC> )

       Purpose

   This UDF is used to add a new record to a CFTS index. An integer 
   representing the record number is returned.

       Parameters

   <CFTShandle> is an integer that references a CFTS index. <expC> is 
   the name of a function that returns as a concatenated string the 
   fields from the .DBF(s) that are to be indexed.

       Returns

   Nothing. If desired, Cfts_Add() can be modified to pass on the 
   integer (beginning with 1) returned by CftsAdd() that corresponds to a 
   record number in the primary .DBF file. This number can be useful in 
   testing the validity of adds. Errors are trapped by Cfts_Err().

       Comments

   Cfts_Add(), in CFTS87.PRG, macro-izes the function name passed as 
   the second parameter to produce the string to be indexed. See the 
   demonstration program BIB.PRG, or SHOW1.PRG for examples of how to use 
   this Clipper feature. The CFTS5.PRG uses the code block feature of 
   CA-Clipper 5.xx to perform this same task.
