When i have the following instruction (for exemple with DW 230 = E4DC and DW 232 = E4DE,) L DW 232 // Load DB 110 L DW 230 // Load DB 111 TNB 99 // Transfert the 99 bytes from the botom to the top, from DB111 to DB110 Is it really how it's works? And in my case DB110 and DB111 are composed of 70 data in Word format so, in totally there is 140 Bytes in each DB. The TNB function is just for the tranfert of the bytes or in my case it's for Words? Or is it just the right byte of each words? I'm a little confused with this function.
