   Hello all,   
      
   I'm Using Borlands Tasm32 v5, and am calling a procedure by pointer (a   
   callback).  The problem is that it doesn't (can't) do any assemble-time   
   checking of the provided arguments, while this does happen when calling the   
   function by value.   
      
   example:   
      
   -- Definition of the procedure   
   TheFunction PROCDESC @@lArgOne:DWORD,@@lArgTwo:DWORD   
      
   -- A by-pointer call   
   mov [@@pFunction],offset [TheFunction]   
   ...   
   call [@@pFunction], eax, 42, -1   ;<- Too many arguments, but not detected.   
      
   -- A by-value call   
   call TheFunction, eax, 42, -1    ;<- detected   
      
   My question, (how) can I tell the by-pointer call which procedure it is   
   targetting, so that its (number and type of) arguments can be checked ?   
      
   Regards,
