[newbie] Computing algorithms

[Dominique Crétel]

Hello,

I would like to write some algorithms with lout.

I would like to get output like those in the article pointed to this
reference
http://www.xcf.berkeley.edu/~jmacd/dcc99.ps

I would like to make two columns (tbl) with the first column containing
something like equations (eqn) with indentation, and the second containing
labels of step of calculation (doc).

So, I think I need to use doc, tbl and eqn, but I don't know hot to do this?

Is there any body who can help me?
Or somebody who already do that?

Thanks,

Dominique Cretel
