帮忙看下什么有关问题好么

帮忙看下什么问题好么？
小弟正在写一段汇编程序
编写计算Y=X^2+6*X+9的程序。

代码如下：

Assembly code

DATA SEGMENTX DB 04HY DB ?DATA ENDSCODE SEGMENTASSUME CS:CODE,DS:DATASTART:PUSH DATAXOR AX,AXXOR CX,CXPUSH AXMOV AX,DATAMOV DS,AXMOV AL,XMOV CL,XMUL CL    MOV BX,AX    ;实现X*X,结果存入BXMOV AX,XMOV CL,1SHL AX,CLMOV DX,AXSHL AX,CLADD DX,AX    ;实现6*X，结果存入DXMOV AX,BXADD AX,DXADD AX,9MOV Y,AXMOV AX,YMOV DL,ALAND DL,0F0HMOV CL,04HSHR DL,CLADD DL,30HMOV AH,02HINT 21HMOV DL,YADD DL,0FHADD DL,30HADD AH,02HINT 21HCODE ENDSEND START

结果，在MASM 5.0编译出错误：
Microsoft (R) Macro Assembler Version 5.00

Object filename [cc33.OBJ]:

50734 + 450386 Bytes symbol space free

3 Warning Errors
1 Severe Errors

求解释啊，求解释


[解决办法]
cc33.asm(9): error A2056: Immediate mode illegal 不该用立即数的你用了
cc33.asm(20): warning A4031: Operand types must match 类型不匹配
cc33.asm(29): warning A4031: Operand types must match
cc33.asm(31): warning A4031: Operand types must match
