Answer 1

改动一下，你试试:
org 0000h
ljmp main
org 0030h
main:
mov r7, #0
mov dptr, #TAB
lcall disp
ljmp main

disp:
MOV P0, R7
mov a, r7
movc a, @a+dptr
mov p2, a
LCALL DEL
inc r7
CJNE R7, #8, disp
RET

DEL:
MOV R2, #10
DEL2: MOV R3, #0
DEL3: DJNZ R3, DEL3
DJNZ R2, DEL2
ret

TAB:
; DB 00H,00H,00H,00H,00H,00H,00H,00H ;
DB 00H,00H,00H,7EH,81H,81H,81H,7EH ;0
DB 00H,00H,00H,00H,00H,82H,0FFH,80H ;1
