The object in this paper is to
examine the value distribution of functions f(z) nonconstant and meromorphic in the
unit disk which have an asymptotic value α, finite or infinite, along a spiral
boundary path. The main result which we prove is that if Δ(r) is a component
of the set of values z such that |f(z) − α| < r, r > 0, which contains a
boundary path on which f(z) tends to α as |z|→ 1, then f(z) assumes
every value in |w − α| < r infinitely often in Δ(r) except for at most two
values (if Δ(r) is simply-connected, then there is at most one exceptional
value).
