I was curious, is there any practical limit on the size of a set (32

smaller sizes to save memory? Perhaps just a historical artifact but
I was curious.
Sorry that was wrong, the biggest size is 32 bytes and the largest
size of an enum is 256 elements. I was talking about sets of enums
also if that wasn’t clear.
I still don’t see it’s possible to make a set which is smaller than 4
bytes, even in the 0..7 range.
program Project1;
{$PackSet 1}
var
a: set of byte;
b: set of 0..7;
begin
writeln(sizeof(a));
writeln(sizeof(b));
readln;
end.
