There's no hexadecimal code for 'dq' (or any other d?) - this directive simply tells the assembler that the following constants shall be put directly into the code (instead of being compiled into some CPU instructions)... I suggest that you add this issue as a request to our bug tracker so that it doesn't get forgotten (I believe that adding it shouldn't be a problem for somebody knowing the related part of FPC).
