The first assembler experiment one

See this blog for the environment: https://blog.csdn.net/qq_41813208/article/details/104418974

Always used masm compiler, link linker, debug debugger, decompilation

Assembler source code 1.asm

assume cs:codesg
	codesg segment
		MOV   AX,4E20H
		ADD   AX,1416H
		MOV   BX,2000H
		ADD   AX,BX
		MOV   BX,AX
		ADD   AX,BX
		MOV   AX,001AH
		MOV   BX,0026H
		ADD   AL,BL
		ADD   AH,BL
		ADD   BH,AL
		MOV   AH,0
		ADD   AL,BL
		ADD   AL,9CH
	codesg ends
end

Enter dosbox

The first step is to compile 1.asm source code production 1.obj

    Execute code through masm.exe file: masm.exe 1.asm compile to generate 1.obj file

The second step is to link 1.obj file to generate 1.exe executable file 

    Generate 1.exe program through link.exe 1.obj command

The third step debugging procedure

     Debug 1.exe program through debug.exe

The whole process
