汇编错误：first.asm<27>:error A2025: Improper align/combine type

[米格315]

代码如下：

;
;first.asm - A first assembly language program ;是一个注释，给出程序first.asm
;
;
;Code segment
;
_TEXT segment word public 'CODE'
assume cs:_Text,ds:_DATA,SS:_STACK
;
;Add two 16 bit values
;
addem proc far ;Entry point from DOS
mov ax,_DATA ;Point the data segment
mov ds,ax ;register to the data
;segment
mov ax,a ;AX=a
add ax,b ;AX=a+b
mov c,ax ;c=a+b
mov ax,4c00h ;AX=No error return
;code
int 21h ;Return to DOX
addem endp
_TEXT ends
;
; Data segment
;
_DATA segment word pubbilc 'DATA'
a dw 3
b dw 4
c dw ?
_DATA ends

;
;Stack segment
;
_STACK segment para stack 'STACK'
dw 128 dup (?)
_STACK ends
end addem ;Defines the entry point

在XP上用MASM 5.0 编译一直报这个ERROR：first.asm<27>:error A2025: Improper align/combine type。
网上查了一天了都不知道是什么原因。哪位朋友知道请指教。

27行：_DATA segment word pubbilc 'DATA'

pubbilc -> public

拼写错误
