LODSD             Load String Doubleword (386)       Flags: O D I T S Z A P C

LODSD

           Logic:        EAX . DWORD PTR (DS:SI)
                         if DF = 0
                             SI . SI + 4
                         else
                             SI . SI - 4

     LODSD loads a doubleword from the memory location at DS:SI into the EAX
     register. SI is then incremented if the direction flag is cleared or
     decremented if it is set.
