this is complete crap. Since D2 uses 32 bit protected mode you have to use 
protected mode code. Since Delphi uses "huge strings" strings have to be 
adressed by Delphi. It should be something like
function DoSomething(S:String):String;
var
  Temp:Pointer;
label
  Action,Done;
begin
     Result:=S;	
     if Length(Result)>0 then
     begin
          Temp:=@Result[1];         // There is a better way to do this, but 
i am not sure how exacltly so i use this
          asm
             push esi               // possibly not needed - see online help 
for ASM  
	       mov esi,offset Result	// Move offset of Result in esi
		 // do processing, example: replace space #32 by #33
Action:      mov al,[esi]
		 inc esi
             cmp al,0
             je  Done
		 cmp al,32
		 jne Action
		 inc al
		 mov -1[esi],al
             jmp Action
Done:		 pop esi
	    end;
	end;
end;

It has. At lease your method of adressing the String content would work if 
you would use protected mode code.
Bis denne ...
