  This investigation is devoted to the program to characterise continuous and
variable discrete asymptotics of solutions to elliptic equations on a manifold
with edge, continued in a cicle of forthcoming expositions [15], [16]. The
structure of continuous and variable discrete (in general branch- ing)
asymptotics is very complex. Therefore, in order to make things more
transparent we present here the approach first in the special constant di-
screte case, based on meromorphic Mellin symbols.
