I'm trying to learn SPARK Ada, and, among other things, I have a procedure =
that simply puts a standard message to the screen. SPARK gives me a warning=
 that the subprogram has no effect; I can see why - it only has the side-ef=
fect of printing to the screen. Everything I can see online to deal with th=
is is a) *very* old, and b) uses SPARK_Io, which I understand is obsolete (=
and which I can't find). So what is the best way to tell SPARK that the pro=
cedure just has that side effect? (Hopefully better than `SPARK_mode =3D> O=
ff').
