Ah, I found Kylix 3 help in home pc.  It is defined in Variants unit.
This is the help text.


--------------------------------------

Specifies string value of Null variants.


Unit

Variants


Category

Variant support routines


Delphi syntax:

var NullAsStringValue: String;


C++ syntax:
extern PACKAGE AnsiString NullAsStringValue;


Description

NullAsStringValue specifies the string that is the result of a
conversion from a Null variant to a string type. By default,
NullAsStringValue is the empty string.

NullAsStringValue is only used when the NullStrictConvert global
variable is set to false.
