section .data
hello: db 'Hello world!',10 ; 'Hello world!' plus a linefeed character
helloLen: equ $-hello ; Length of the 'Hello world!' string

section .bss
num: resb 1
q: resb 1
r: resb 1

section .text
global _start

_start:

mov [num],byte 34

mov ax,[num]
mov bl,10
div bl

add al,'0';
mov [q], al
add ah,'0';
mov [r], ah

mov eax,4
mov ebx,1
mov ecx,q
mov edx,1
int 80h

mov eax,4
mov ebx,1
mov ecx,r
mov edx,1
int 80h


mov eax,1
mov ebx,0
int 80h;

Name of the variable is hello. Its length is the  numeric constant 13. 12 + 1 for the linefeed. Stored in helloLen variable.

In a computer programme, information is stored in variables so that it may be accessed and changed. They also give us a means to give data a name that is descriptive, making it easier for us and the reader to understand our programmes.

It can be useful to conceive of variables as data storage units. They exist only to label and keep data in memory. Your software can then make use of this data.

.data

 hello2: db 'Hello World! G',10

 helloLen2: equ $-hello2

and in main

   int 80h;

   mov edx,helloLen2

Use the below option to generate a listing file, the hex values will display the length, look for the mov,edx,length_Var instruction line on the right hand side (RHS).
