2002-11-01 schirmer 2002-11-01 Inserted some extra paragraphs in large proofs to make tex run...
2002-10-31 schirmer 2002-10-31 "Definite Assignment Analysis" included, with proof of correctness. Large adjustments of type safety proof and soundness proof of the axiomatic semantics were necessary. Completeness proof of the loop rule of the axiomatic semantic was altered. So the additional polymorphic variants of some rules could be removed.
