2009-04-20 haftmann 2009-04-20 power operation on functions with syntax o^; power operation on relations with syntax ^^
2008-10-07 haftmann 2008-10-07 arbitrary is undefined
2007-07-11 berghofe 2007-07-11 Renamed inductive2 to inductive.
2006-12-11 berghofe 2006-12-11 Adapted to new inductive definition package.
2005-06-17 haftmann 2005-06-17 migrated theory headers to new format
2004-06-21 kleing 2004-06-21 Merged in license change from Isabelle2004
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.
2002-07-16 schirmer 2002-07-16 Added conditional and (&&) and or (||).
2002-07-12 schirmer 2002-07-12 little Bugfix
2002-07-10 schirmer 2002-07-10 Added unary and binary operations like (+,-,<, ...); Added smallstep semantics (no proofs about it yet).
2002-02-22 schirmer 2002-02-22 Added check for field/method access to operational semantics and proved the acesses valid.
