d3f2015ae170a15e5b57d4880ded53073d725ac0Till Mossakowski proposed formalism/language when writing a
d3f2015ae170a15e5b57d4880ded53073d725ac0Till Mossakowski specification. Our goal here is to provide a companion

d3f2015ae170a15e5b57d4880ded53073d725ac0Till Mossakowski developed this method for the (logical-algebraic)

d3f2015ae170a15e5b57d4880ded53073d725ac0Till Mossakowski challenge is that a method that is too general does not
d3f2015ae170a15e5b57d4880ded53073d725ac0Till Mossakowski encompass the different kinds of systems to be studied,
d3f2015ae170a15e5b57d4880ded53073d725ac0Till Mossakowski while too many different specialized methods and

d3f2015ae170a15e5b57d4880ded53073d725ac0Till Mossakowski precisely, we consider here that a software item may be

d3f2015ae170a15e5b57d4880ded53073d725ac0Till Mossakowski or a data structure. We also support both

d3f2015ae170a15e5b57d4880ded53073d725ac0Till Mossakowski functional programming languages. In previous work, we
d3f2015ae170a15e5b57d4880ded53073d725ac0Till Mossakowski have introduced a Hoare calculus for partial
d3f2015ae170a15e5b57d4880ded53073d725ac0Till Mossakowski correctness of monadic programs. All this has been done
d3f2015ae170a15e5b57d4880ded53073d725ac0Till Mossakowski in an entirely monad-independent way. Here, we extend
d3f2015ae170a15e5b57d4880ded53073d725ac0Till Mossakowski this to a monad-independent dynamic logic (assuming a

d3f2015ae170a15e5b57d4880ded53073d725ac0Till Mossakowski monad). Dynamic logic is more expressive than the Hoare

d3f2015ae170a15e5b57d4880ded53073d725ac0Till Mossakowski termination and total correctness. As the background
d3f2015ae170a15e5b57d4880ded53073d725ac0Till Mossakowski formalism for these concepts, we use the logic of
