Numerical Value

[I_Hate_Assembly]

Hi everyone

I would like to know how I can display a numerical value in this small program.

Code Select Expand



.model small
.stack 64
.data


.code
xyz PROC NEAR

mov AX, @DATA
mov DS, AX
mov AX ,5
mov BX, 3
call SUM

; un probleme ici
MOV AH,09h
MOV DX,AX
INT 21h

mov ah, 4ch
int 21h

xyz endp

SUM PROC NEAR
ADD AX,BX

RET
SUM endp


end



Thanks in advance  :U

you have a 16-bit binary value
you need to convert that to an ASCII numeric string for display (presumably decimal)
the code depends on whether you want to display signed values (-32768 to 32767) or unsigned (0 to 65535)

lazy method - you could display it in ASCII hexidecimal format and let the reader decide how to interpret it   :P

Thank you for your answer  :U

Where can I find the appropriate syntax ?

I looked up for it in the web but I did not find anything standard to do that.

[dedndave]

there are routines if you search the forum
i have one called ling long kai fang in another thread, but that is 32-bit and it will display huge integers - kind of overkill

let me know whether you want a signed or unsigned routine

[I_Hate_Assembly]

Let's start with a routine for unsigned, so I can understand it  :P

Thank You

ok - give me about 15 minutes - then it's nap-time   :bg

[I_Hate_Assembly]

Ok no problem take your time.  :U

Thanks

[dedndave]

give this a try - i did not test it   :P

[I_Hate_Assembly]

I will .. Thanks !  :U

[I_Hate_Assembly]

I added a line to wait a key press from the keyboard and I get the value but also with a write fault. :P

Thanks !

:bg

just add this before you terminate

        mov     ah,0
        int     16h

[I_Hate_Assembly]

I already added the first one before terminating the program.
Does the second one fix the bug ?

[dedndave]

i don't understand the write fault ???
anyways - here is the modified program...

[I_Hate_Assembly]

yes when the program asks for a key to be pressed the message appear

[dedndave]

you'll have to show me the error message - the program runs fine, here
i am using xp pro sp2
