Hi Hamish & Markus,
Thanks for the quick replies. I did have a look around the documentation for
the functionality provided by r.univar, but I think the fact that I couldn't
see it in any of the relevant examples put me off track.
The comment solution makes sense, and I don't think it is a file that needs
extensive commenting, but coming from a UNIX background the hash marks screamed
comment at me - maybe angle brackets would be a better choice in the
documentation:
<--------- start of control file ----->
I will try again later with them removed anyway.
Cheers,
Jamie

historical footnote: I wrote r.univar(.c) because I didn't notice that
the earlier r.univar(.sh) existed until I was near done. I guess the
same thinness in the docs still exists. Happy mistake. ;-)

imagery/i.atcorr/GeomCond.cpp's GeomCond::parse():
cin >> igeom;
cin.ignore(numeric_limits<int>::max(),'\n'); /* read the rest of the
scraps, like comments */
...
can a C++'er recommend ways to silently skip empty lines and lines
beginning with '#'?
thanks,
Hamish
