[fpc-pascal] Inline ASM code

[LacaK]

Hi *,

I need store result of floating point calculation (in my example 
arctan()) in memory pointed by some variable. See this code:
var a: single; pa: PSingle;
   asm
       fild dy
       fild dx
       fpatan
       fstp a
       fwait
   end;
   pa^ := a;

It works, but is there any way how to store result directly to "pa^" in 
assembler ?
I have tried:
       ...
       fpatan
       fstp pa^ ... fstp (pa) ... but this does not compile ... I need 
store to memory location pointed by pa "variable"
       fwait
   end;

Thanks
-Laco.
