Yes, it is a bit bizarre. It's not much of a problem for me since I've
written a program that generates boards from a set of problems. The Lout
output is automatically generated.
You could go even further. There is a very nice TeX package (chess
something (of course :)) that helps chess writers to typeset a whole game.
Apparently the thing understands moves. So initially, the board is in its
starting position, then you say you make the move e2-e4 and the board is
automatically updated. Then you can say showboard or something and the
current board is shown. This prevents you from making a lot of mistakes
(not that I've used it in that way though).
I used it to generate my boards before I started exploring Lout. I got a
bit annoyed by the fact that I couldnt't place my board the way I wanted
to. I also had to generate new fonts for every size of the board. Lout
is much more flexible in this :).
Which brings me to another question; TeX is a programming language with
loops, if statements, ... Lout doesn't seem to have such constructs (or am
I mistaken?) Why?
