Look in the reference manual for the "string" type

  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.
