Subject:      Storing expressions

Ok, since we have to check for errors in our expressions before we output any of the instructions, what is an acceptable way of storing them? The spec says they are of "arbitrary length", so how do we go about this using a static array? I don't see a way of dynamically allocating space in Pascal, anyone know if Prof. Edwards said anything about storing the expressions in class and I just didn't catch it? Any help would be appreciated.
