Are you sure? The order of statements makes a difference here within a sequential process.

You're right and that was silly of me. I pared down something else and posted quickly. A real example would be: 


if rising_edge (clk) then
  a <= a + 1;
  if (a = 23) then
    b <= '1';
  else
    b <= '0';
  end if;
end if;

where is doesn't matter if the increment is before or after the comparison - you get exactly the same behaviour either way.

Mark.
