DSEG SEGMENT
   VAR1 DB "ABCDEF T YQ0",0
DSEG ENDS
CSEG SEGMENT
  ASSUME CS:CSEG ,DS:DSEG
START:
  MOV AX,DSEG
  MOV DS,AX
  LEA SI,VAR1
  mov bx,si        ;bx和si同时指向数组
NEXT:
  CMP BYTE PTR [SI],00H
  JZ EXIT
  CMP BYTE PTR [SI],20H
  JNZ DISP1
DISP:
  inc si            ;遇到空格不保存
  jmp next
DISP1:
    mov al,[si]
    mov [bx],al        ;非空格和0保存（原数组位置）
  INC SI
  inc bx
  JMP NEXT
EXIT:
    mov [bx],0        ;数组最后保存个0
  MOV AH,4CH
  INT 21H
CSEG ENDS
END START

mov [bx],0

楼上的大侠，这句应该改成这样 mov byte ptr [bx],0;
