nas汇编程序的调试排错方法

nas汇编程序的调试排错方法：
1、查找是哪一步错了
2、查看对应的*.lst文件，本例中是"asmhead.lst"
3、根据*.lst文件的[ERROR #002]提示查看源码，改错。
4、重新运行编译，OK

1、查找是哪一步错了：

nask.exe编译汇编程序时出错了

//----------------------------
//运行boyI报错：
E:\techdoc\30dayOS\code\day03\boyI>..\..\tolset\z_tools\make.exe
make.exe -r img
make.exe[1]: Entering directory `E:/techdoc/30dayOS/code/day03/boyI'
make.exe -r haribote.img
make.exe[2]: Entering directory `E:/techdoc/30dayOS/code/day03/boyI'
nask.exe ipl10.nas ipl10.bin ipl10.lst
nask.exe asmhead.nas asmhead.bin asmhead.lst
NASK : 1 errors.
make.exe[2]: *** [asmhead.bin] Error 1
make.exe[2]: Leaving directory `E:/techdoc/30dayOS/code/day03/boyI'
make.exe[1]: *** [img] Error 2
make.exe[1]: Leaving directory `E:/techdoc/30dayOS/code/day03/boyI'
..\..\tolset\z_tools\make.exe: *** [default] Error 2E:\techdoc\30dayOS\code\day03\boyI>

2、查看对应的"asmhead.lst"文件：

在文件中根据关键字"[ERROR"查找就可以了。
E:\techdoc\30dayOS\code\day03\boyI\asmhead.lst

    23 0000C20B C7 06 0FF4 0140                 	MOV WORD [SCRNX],32024 0000C211                                 	MOV WROD [SCRNY],200>> [ERROR #002] parameter error.25 0000C211 66 C7 06 0FF8 000A0000          	MOV DWORD [VRAM],0x000a000026 0000C21A                                 	;用BIOS取键盘上各种指示灯的状态27 0000C21A B4 02                           	MOV AH,0x02

3、根据"asmhead.lst"文件的[ERROR]提示查看源码

24 0000C211 MOV WROD [SCRNY],200
>> [ERROR #002] parameter error.
查看"asmhead.nas"汇编程序源码：MOV WROD [SCRNY],200
错误原因：WORD写成了WROD
修改为：MOV WORD [SCRNY],200

4、重新运行编译，OK
