[ ] ---> optional
< > ---> mandatory
example :-
data x type i.
data y type i.
data z type i.
x = 10.
y = 20.
z = x + y.
write z.
example :-
data : x type i,
y type i,
z type i.
x = 10.
y = 20.
z = x + y.
write z.](https://image.slidesharecdn.com/abapbasics01-101007021958-phpapp01/85/Abap-basics-01-2-320.jpg)
