var
	byteset : Tbyteset;

begin
	byteset := []; // empty set
	byteset := [0, 3, 101]; // puts literal values into the set
	Include(byteset, 27]; // or byteset := byteset + [27];
	Exclude(byteset, 3); // or byteset := byteset - [3];
end;

Note that set types are limited to 256 elements of ordinal types 
(integer, char or enumeration).
