About article:
We investigate the subsets of the Fr\'echet space $s$ of all sequences of real
numbers equipped with the Fr\'echet metric $\rho$ from the Baire category point of view.
In particular, we concentrate on the ``convergence" sets of
the series $\sum f_n \left(x_n\right)$ that is, sets of sequences $x=(x_n)$
for which the series converges, or has a sum (perhaps infinite), or oscillates.
Provided all $f_n$ are continuous real functions, sufficient
conditions are given for the ``convergence" sets to be of the first Baire
category or residual in $s$.
