OK, I must confess: I covered up some.

After a few hours spent trying to figure out from Companion2ed p843  
how to do a "command definition", the best I could come up was:

	\newcommand{\mysection}[2]{\section \label{421}}

which, when I typed "\mysection{this and that}" gave me both the  
correct section number in the body and it the toc but, in both  
places, without "this and that" and sure enough without \label{421}.

The 421 was an experiment: I was hoping eventually to replace 421 by  
a command that would automatically put "the next number" (as opposed  
to a random one) which I would then look up anytime I would need to  
make a reference.

So, really, I have two problems:

—the fact that I can't write the \newcommand but which I hope  
eventually to figure it out which is why I didn't mention it,
—the one I know I have no chance whatsoever to solve which is the one  
I asked about, namely how to get a command that generates "the next  
number" from a counter or the chapter-section number of the section.

Hopeful regards
