e.g.: Take the example from MIA 90-02(1.3) August 1994, page 15 and 16:
(shortened)

"Introduce the following SLOTs: (filename 'stack.bet')
  ORIGIN '~beta/basiclib/current/betaenv';
  BODY 'stackImp'
  --- Lib: attributes ---
  stack:
    (# element:, Object;
       private: @<<SLOT private: descriptor>>;
       push: (# (* some code with another slot *) #);
       (* more attributes *)
     #)

Create a new fragment file 'stackImp.bet':
  ORIGIN 'stack';
  --- private: descriptor ---
  (# A: ,[100] ^element;
     top: @intger;
  #)
  (* some more fragment descriptions *)    "

I am useing the Mjolner Beta System 5.0(2) for Linux(Intel 386/486) and
I can not compile the library fragment 'stack.bet'. After typeing
'beta stack' I get the following message:

Mjolner BETA System version 5.0(2) for Linux(Intel 386/486)

">>" means that this is one line.

But I can compile an ordinary program fragment useing the library, e.g.:
  ORIGIN '~beta/basiclib/current/betaenv';
  INCLUDE 'stack'
  -- program: descriptor --
  (# myStack: stack (# element:: IntegerObject #);
     A: @myStack
     do (* some code *)
   #)

As far as I understood, the fragment system should include the facility
to compile fragments seperatly. So what did I do wrong?
