hye i try to use "org" command on dseg and somhow it's not working
there is some of my code that i write
dseg segment
N1 db 6
org 10h
TABLE1 db 3,12h,13h,15h,34h,7Ah
N2 db 5
org 30h
TABLE2 db 4,12h,14h,15h,87h
dseg ends

cseg segment
assume ds:dseg, cs:cseg

begin: mov ax,dseg
mov ds,ax

;--- cecking for equal values & coping unique values ----

mov ax,0 ;<=== reset regiter AX to 0
mov bx,0 ;<====reset counter to 0
mov cx,0 ;<=== reset counter2 to 0
mov bl,N1[0] ;<=== move value from N1 to register BL
mov cl,N2[0]
mov di,0 ;<=== move pointer DI to the first cell
mov si,0 ;<=== move pointer SI to the first cell
start: mov al,TABLE1 [si];<=== transfer value from TABLE1 array to register AL
mov ah,TABLE2 [di];<=== transfer value from TABLE 2 array to register AH
cmp al,ah
je eqq
jne neq



if someone can help to understand why if i use org commend it not working well

0. Welcome to the FASM forum Smile

1. Please use [ c o d e ] tags

2. FASM doesn't support "assume" ... please RTFM (the official FASM manual), check what assembler you actually use, and check the FAQ's in this forum Smile

PS: org doesn't affect data ... it affects absolute addresses only http://flatassembler.net/docs.php?article=manual#2.2.4

(someone move in into Main please, I can't)

golant85,

That source looks like MASM fragment. With slight ornamental works it compiles and links fine. Thus I deduce that you're trying to compile MASM source with fasm (or, in other words, don't understand what you're doing).
