新手啊，请越详细越好

好好看书比什么都强。解释不太清楚的地方还是自己好好学习吧。
var_2 = word ptr -2\*定义VAR_2等于word类型的-2
arg_0 = word ptr 4\*定义arg等于word类型的4，下同。
arg_2 = word ptr 6
arg_4 = word ptr 8
arg_6 = byte ptr 0Ah\*定义arg等于byte类型的0A（10），下同
arg_A = byte ptr 0Eh
arg_E = word ptr 12h
arg_12 = byte ptr 16h
arg_16 = word ptr 1Ah
arg_18 = word ptr 1Ch

push bp\*中断压栈
mov bp, sp
sub sp, 2
push si \*原址压栈
mov si, [bp+arg_0]\*中断处理程序地址，下面开始中断处理程序。
