Hi Sam:

   I'm very grateful for your ideas: they solve the problem partially.
The dependence of the "duda" macro of a paragraph is a bit annoying,
because sometimes the associated paragraph can be very long. In other
occasions I have the need to include 2 or 3 consecutive "duda" macro
without available paragraph to attach to. In this last case is where
the macro you proposed is problematic.

   So my question is: Is it possible to write a macro which according
to some true or false value of a variable, includes a remark or leaves
the text untouched respectively?
