USING NASM SYNTAX
One use of the rcl and rcr instructions is in multiprecision arithmetic. For example, the 8086 is limited to 16-bits, so how could one represent a 32 bit number? The obvious way is to use two 16 bit registers. For example, if an unsigned 32-bit number, named A, is stored in dx:ax (top 16 bits in dx, and the lower 16 bits in ax) we could multiply A by 2 by using a left shift followed by a rotate through carry left as follows: shl ax,1 rcl dx,1 Write a NASM program which will: 1. Display your name on the screen 2. Prompt the user to enter a 32-bit base-2 number from the keyboard. 3. Read the number, storing it into the register pair dx:bx. 4. On a new line, display an appropriate label and the number as a 32-bit binary number. 5. Ask the user if he/she wishes to read and display another number, and repeat from step 2 until the user is done.
