Hi,

I know that AD is field/variable specific. But when I code following and execute on MF the o/p gets displayed in RED color (though AD=R is right justified, not sure if it applies to text as well. Seems NO from the output). Something happens at Natural back to change the default color?

```auto
WRITE 30X 'WELCOME TO NATURAL' (AD=R)
END
```

Also if AD=R doesn’t applies to the text within WRITE/DISPLAY, then shouldn’t it be a syntax error as it differ its function.

Hi Ats,

I think it makes not much sense to right or left justify a constant. But I agree it can confuse and the doc is not consistent. :?

Perhaps it is a reminiscence of an older Natural version that this was accepted as colour attribute (and still is). :idea:

Following work all the same:

```auto
WRITE 'WELCOME1' (AD=R)
/ 'WELCOME2' (RE)      
/ 'WELCOME3' (CD=RE)   
END
```
