[求助] 子程序参数传递问题

请问，下面我的程序错了什么问题
这个程序是实现两个已定义数组分别求和
DATA SEGMENT
ARYA DB 06H,23H,0AH,2FH,1EH
SUMA DW ?
ARYB DB 0BH,21H,11H,3AH,4EH,10H
SUMB DW ?
DATA ENDS
CODE SEGMENT
ASSUME CS:CODE ,DS:DATA
START:
MOV AX,DATA
MOV DS,AX
MOV AX,SUMA-ARYA
PUSH AX
MOV AX,OFFSET ARYA
PUSH AX
CALL SUM
MOV AX,SUMB-ARYB
PUSH AX
MOV AX,OFFSET ARYB
PUSH AX
CALL SUM
MOV AH,4CH
INT 21H
CODE ENDS

PROCE SEGMENT
ASSUME CS:PROCE,DS:DATA
SUM PROC FAR
PUSH AX
PUSH BX
PUSH CX
PUSH BP
MOV BP,SP
PUSHF
MOV CX,[BP+14]
MOV BX,[BP+12]
MOV AX,0
LP:ADD AL,[BX]
ADC AH,0
INC BX
LOOP LP
MOV AX,[BX]
POPF
POP BP
POP CX
POP BX
POP AX
RET 4
SUM ENDP
PROCE ENDS
END START
