  We obtain a classification of the finite two-generated cyclic-by-abelian
groups of prime-power order. For that we associate to each such group $G$ a
list $\inv(G)$ of numerical group invariants which determines the isomorphism
type of $G$. Then we describe the set formed by all the possible values of
$\inv(G)$. This allows computer implementations for constructing all the
finite-two generated cyclic-by-abelian groups of a given prime-power order,
computing the invariants of such a group, and to decide whether two such groups
are isomorphic.
