--------------------------------Question
Write a 32-bit x86 assembly program that performs the following operations:
Part 1: Swaps content of EBX as follows:
Requirement: Store 'A' in EBX LSB or BL, store 'B' in BH, and then swap BL and BH. You will have to use a temporary storage, you can use EAX (use AL) or any storage you may define.
For example: Content of EBX at init: 00000000, then after storing A and B: EBX = 00004241 ; 4241=ASCII codes in Hex
After swapping: EBX = 00004142 which is BA
------------------------------------------------------------
NOT WORKING CODE:
.386 .model flat, stdcall .stack 4096 .data
.code main PROC
MOV BL, 'A' MOV BH, 'B' MOV AL, BL MOV BL, BH MOV BH, AL
INVOKE ExitProcess, 0 main ENDP END main
