pascal and learning 3d

[User137]

I don't know exactly how it goes, but i tested a bit too after your comment. TRGB2 is indeed 3 bytes for some reason.

But these are both 8 bytes, and 5 if packed. Same with Lazarus and Delphi.

TRecord1 = record
  a: single;
  b: byte;
end;

TRecord2 = record
  b: byte;
  a: single;
end;

So it doesn't matter if the value is last one. Having only 1 variable type in record seems to be special case, that is not adding any padding.
