__fastcall TDBISAMFunctionParam(TDBISAMFunctionParams*
      AFunctionParams)

Use the New operator to create an instance of a TDBISAMFunctionParam object using the constructor. However, you should never need to create an instance of the TDBISAMFunctionParam object since one is automatically created when using the CreateFunctionParam method of the TDBISAMFunctionParams object.
