Jakash3 - Assembly Tutorial: Basic Commands

Jakash3 runs through some basic assembly commands using debug.exe. Debug is a 16bit disassembler/assembler that can be found in msdos and all 32bit versions of windows. If you are using a 64bit windows then you will need to get dosbox.

@mohamed912mm damn, i dont remember writing that. It has been a while since I done asm. mohamed... if you're using 32bit assembly don't use 16bit registers like that. use 32 registers. "mov eax,123"

@asmcriminaL sorry forgot to mention that, bx will contain 34, which is byte 0 of the variable and omit the mov ax,variable1 instruction, it's just a wasted instruction don't know why i typed it.

[asmcriminaL]

2:27, 34h is in AH, which is 1byte,

if you do

variable1 word 1234h

mov ax,variable1

mov bx, byte ptr [variable1]

which is byte 0 since the array index starts at 0, so al is actually byte 0, and ah is byte 1
