We introduce a domain-free λµ-calculus of call-by-value
as a short-hand for the second order Church-style.
Our motivation comes from the observation that
in Curry-style polymorphic calculi, control operators such as
callcc-operators cannot, in general, handle correctly
the terms placed on the control operator's left, so that
the Curry-style system can fail to prove the subject reduction property.
Following the continuation semantics,
we also discuss the notion of values in classical system,
and propose an extended form of values.
It is proved that the CPS-translation is sound with respect to
domain-free λ2 (second-order λ-calculus).
As a by-product, we obtain the strong normalization property
for the second-order λµ-calculus of call-by-value in
domain-free style.
We also study the problems of type inference, typability, and
type checking for the call-by-value system.
Finally, we give a brief comparison with standard ML plus callcc,
and discuss a natural way to avoid the unsoundness of ML with callcc.
