帮我改进以下代码CRLF MACRO MOV DL,0DH MOV AH,2 INT 21H MOV DL,0AH MOV AH,2 INT 21H ENDM STACK SEGMENT STACK DW 100 DUP(?) STACK ENDS

代码看起来没有问题,但是如果你想改进 CRLF 宏,可以添加一个参数来指定换行符的数量,这样可以更方便地定制换行符的数量。
例如,下面是修改后的 CRLF 宏:
```
CRLF MACRO count
MOV CX, count
mov DL, 0DH
MOV AH, 2
@@:
INT 21H
mov DL, 0AH
INT 21H
loop @b
ENDM
```
使用方法:
```
CRLF 2 ; 输出两个换行符
```
希望对你有所帮助。

CRLF MACRO MOV DL,0DH MOV AH,2 INT 21H MOV DL,0AH MOV AH,2 INT 21H ENDM STACK SEGMENT STACK DW 100 DUP(?) STACK ENDS这段代码怎么去掉crlf
如果你想在代码中去掉 CRLF 宏,可以直接删除 CRLF 宏的定义以及在代码中使用 CRLF 的部分。
例如,以下是去掉 CRLF 的代码:
```
MOV AX, @DATA
MOV DS, AX
MOV AX, @STACK
MOV SS, AX
MOV DX, OFFSET STRING
MOV AH, 9
INT 21H
MOV AH, 1
INT 21H
SUB AH, AH
SUB AL, 30H
MOV CX, AX ; 输入的数
MOV AX, 1 ; 计算阶乘
LP:
MUL BX
INC BX
CMP BX, CX
JBE LP
LEA DI, BUF
MOV BX, 10
MOV CX, 16
LOOP1:
XOR DX, DX
DIV BX
ADD DL, '0'
MOV [DI], DL
INC DI
DEC CX
JNZ LOOP1
MOV SI, OFFSET BUF + 15
DISPLAY:
MOV DL, [SI]
MOV AH, 2
INT 21H
DEC SI
CMP SI, OFFSET BUF - 1
JNB DISPLAY
MOV AH, 4CH
INT 21H
```
注意,如果你需要输出换行符,可以在 DISPLAY 循环结束之后手动输出换行符。例如,可以在最后添加以下代码来输出一个换行符:
```
MOV DL, 0AH
MOV AH, 2
INT 21H
```
