我是初学者,帮忙改一下程序谢谢!

data segment
buf db 23h,16h,08h,20h,64h,8ah,91h,35h,2bh,0ffh
cn equ $-buf
data ends
stack segment
sta db 10 dup(?)
top equ $-sta
stack ends
code segment
assume cs:code, ds:data, ss:stack
start:
mov ax,data
mov ds,ax
mov bx,offset buf
mov cx,cn
dec cx
mov al,[bx]
inc bx
lp:cmp al,[bx]
jbe next
mov al,[bx]
next:inc bx
dec cx
jnz lp

mov bl,al
and al,0f0h
mov cl,4
shl al,cl
add al,30h
mov dl,al
mov ah,02h
int 21h
and bl,0fh
add bl,30h
mov dl,bl
mov ah,02h
int 21h

mov ah,4ch
int 21h
code ends
end start
怎样让这段程序找出最大值!要怎么改呢?急,谢谢大家了

[samsun2000]

lp:cmp al,[bx]
jbe next
mov al,[bx]
next:inc bx
dec cx
jnz lp
上面这段作完，al里面就是最大值啦。你到底要干嘛？

[zheyong0501]

这是最小值啊

[samsun2000]

那你把
lp:cmp al,[bx]
jbe next
mov al,[bx]
next:inc bx
dec cx
jnz lp
里面的第二句改成jge next看看

[dongyi940333]

试试看这个:

data segment
buf db 23h,16h,08h,20h,64h,8ah,91h,35h,2bh,0ffh
cn equ $-buf
data ends



code segment
assume cs:code, ds:data
start:
mov ax,data

mov ds,ax



mov cx,cn

dec cx

mov si, 0

mov al, [si]

s:

cmp al, [si+1]

ja next

mov al, [si+1] ;保存最大的



next:

inc si

loop s

mov ah,4ch

int 21h

code ends

end start

初学不对之处请原谅

测试:
在命令行中进入TC根目录
输入 BGIOBJ EGAVGA TLIB LIB\GRAPHICS.LIB+EGAVGA
这2个命令将生成图形的连接文件
然后在程序的
initgraph(&driver,&mode,"");前加入：
registerbgidriver(EVAVGA_driver);
