Do these comments in Tlbx CfByeOrder.incl /* not easily translatable into FB CFSwapInt64HostToBig CFSwapInt64BigToHost CFConvertFloatHostToSwapped CFConvertFloatSwappedToHost CFConvertDoubleHostToSwapped CFConvertDoubleSwappedToHost */ mean that there is no way currently to fix legacy data if it is a 'single' type variable?
