\ <A ( -- -1 ) Entry attributes description
\ >B ( colour -- x ) Colour is Background colour
\ >F ( colour -- x ) Colour is Foreground colour
\ Attributes may be used freely
\ A> ( -1 x .. x -- attr )
\ Return over all attribute
\ only 12 Bits are used up to now!
\ SET-ATTR ( attr -- ) Send attributes to terminal
\ To do: Make <A A> State smart and compile
\ only literals!
