title:  dc.b    '**   tile   **',0
buffer:	ds.b	80
skipln:	dc.b	0
prompt: dc.b    'Please Enter your birthday (xx/xx/xxxx) ...',0        
answer:	dc.b	'* On xx/xx/2008, you will be '
age:	ds.b	8
period:   dc.b   '.'
stars:	dcb.b	40,'*'
end

can anyone explain to me why the period goes on the next line?
i've been playing around with it for quite a while, any constructive criticism is welcome.

thanx in advance.
