I used a metodwith function word_to_2byte and byte_to_8bool, but it is too complicated to obtanin a single bit. Is there some more efficient metod? Could you explain me how? Tankyou David

	Regards, Jacek What is confusing you is the fact that you never see a number but always its digit representation. So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded. #StayWithUkraine
