Edge Effects of Call Edges In analogy to the concrete semantics we define, as a first step, for each complete lattice D, for monotonic edge effects [[k]] , and for monotonic functions enter and combine the abstract transformation effected by a same-level computation: [[π k]] = [[k]] ◦ [[π ]] for a normal edge k [[π1 〈f〉π2 〈/f〉]] = H ([[π2]] ) ◦ [[π1]] for a procedure f where the transformation
