I'm trying to write inline assembly in lazarus but I get several error messages like this:

Code:
Error: Unknown identifier "EAX"



Code:
unit unt_asm;
{$mode objfpc}{$H+}
//[...]
procedure TForm1.btnGoClick(Sender: TObject);
var
  num, answer : integer;
begin
  num := StrToInt(edtInput.Text);
  asm
    MOV EAX, num
    ADD EAX, 110B //add binary 110
    SUB EAX, 2    //subtract decimal 2
    MOV answer, EAX
  end;
  edtOutput.Text := IntToStr(answer);
end;
end.


How can I fix these errors?

//edit: Fixed myself, I've missed the line {$ASMMODE intel}

Was gonna mention that hehe. By the way, here's a neat trick.

{$ASMMODE intel}
{$IFDEF CPUX86}
asm
//ASM
{$ELSE}
{$IFDEF CPUX64}
asm
//ASM
end;
{$ENDIF CPUX64}
{$ENDIF}

This way you can write different code for 32 and 64 bit (comes very handy).
