samir,

Do not double post in this forum. I moved your question to the 16 bit forum so you had a better chance of getting an answer.

Do you mean numbers of 2 digits?

How do you enter the 5 numbers? This is the most important part because finding the largest one is too easy to mention.

This looks like a school assignment and the numbers are to be entered using the Irvine library.

it is school assignment , user enter 5 nomber ( in array maybe ) and the programme find the max of the nombers

This can't be "may be", it is the most important part.
Once you have the five numbers it is uncomplicated to sort them.

You can do a Bubble Sort, for instance. Just in case you don't know what was that, I searched the wikipedia for you:

"The algorithm starts at the beginning of the data set. It compares the first two elements, and if the first is greater than the second, it swaps them. It continues doing this for each pair of adjacent elements to the end of the data set. It then starts again with the first two elements, repeating until no swaps have occurred on the last pass. This algorithm's average time and worst-case performance is O(n2), so it is rarely used to sort large, unordered data sets. Bubble sort can be used to sort a small number of items (where its asymptotic inefficiency is not a high penalty). "

PS: I read again what you want, the maximum, so you don't even need to sort the array.

Of course, if you don't have the slightest idea of the x86 instruction set it might be a nightmare. You have my sympathy if this is the case.

Here is the code, but be aware that your teacher may come here :

Code: [Select]
`;ml /c test.asm;link16 /tiny test.obj.186code  segment      assume  cs:code,ds:code      org     100hbegin:      jmp     start inArray db 5 dup(0); enterMsg db "Enter 5 Numbers between 00 and 99.",13,10,"\$" enterNumb db 13,10,"Enter Number: \$" sayMaximum db 13,10, "Maximum number is: \$" errmsg db 13,10,"Invalid input\$" numCount dw 5 maxNum db ?start: mov dx,offset enterMsg mov ah,09h int 21h inpStart: cmp numCount,0 jz inputEnd mov dx,offset enterNumb mov ah,09h int 21h dec word ptr numCount call getNumber jc error1 mov si, offset inArray add si, numCount mov byte ptr [si], al jmp inpStart inputEnd: mov cx, 0 mov al, 0 mov si, offset inArray dec silooper: inc si cmp cx, 5 jae looperExit add cx,1 cmp al, byte ptr [si] ja looper mov al, byte ptr [si] jmp looperlooperExit: mov maxNum, al mov dx, offset sayMaximum mov ah,09h  int 21h xor ax, ax mov al, maxNum mov dx, 10 div dl push ax mov dl, al add dl, 30h mov ah, 2 int 21h pop ax mov dl, ah add dl, 30h mov ah, 2 int 21h mov ah, 4ch int 21h error1: mov dx,offset errmsg mov ah,09h int 21h mov ah, 4ch int 21h getNumber  proc near ; Accepts only 00 to 99 sub bh,bh mov dl,10 mov ah,1 int 21h cmp al,"0"                  jb g_error                cmp al,"9" ja g_error sub al, 30h mul dl                      jc g_error                cmp al, 100 ja g_error mov bh, al mov ah,1 int 21h cmp al,"0"                  jb g_error                cmp al,"9" ja g_error sub al, 30h add al, bh clc retg_error:      stc retgetNumber  endpcode  endsend  begin`

Enter 5 Numbers between 00 and 99.

Enter Number: 21
Enter Number: 66
Enter Number: 43
Enter Number: 61
Enter Number: 09
Maximum number is: 66
