If I have have a set with < 9 elements, like : type TMyEnum = ( xOne, xTwo, xThree, xFour, xFive ); // Count <= 8, fits in one Byte TMyEnums = set of TMyEnum;
then in Delphi a variable of that type can be casted to Byte. Other casts don't work. In FPC I must cast it to Integer! Does it really mean that all sets in FPC reserve at least 32 bits? Is it documented? I did not find it as "Set" gives so many false matches. I hope the implementation is otherwise compatible with Delphi, meaning that the bits start from LSB always. I rely now on this implementation detail. There is code that transfers bitfields between computers. Using type checking and descriptive names makes the code better in many ways, compared to using integers & AND operator.
