Gaby,

could you please elaborate?  I found this on the wiki:

(1) -> a := 'x :: OutputForm

   (1)  x
                                                             Type: OutputForm
(2) -> b := 'y :: OutputForm

   (2)  y
                                                             Type: OutputForm
(3) -> a and b
 
   Argument number 1 to "and" must be a Boolean.


I'd like to know what exactly was moved from the interpreter to the algebra!

many thanks,

Martin
