I am writing mathematics, hence have theorems, lemmas etc. I can use \newtheorem in the usual way to get my things labelled appropriately with Theorem 6.2 and Lemma 4.5 etc. However I do not like having all the theorems typeset in italics. I would like to change the "theorem-like environment" so that the theorems are typeset in slanted type. The LaTeX book does not mention at all how to do it, or in fact where the "theorem-like environment" is defined.... I would be grateful if anyone could help. Thanks Gordon gordon@cs.uwa.oz.au

I'll take this one because its so easy. It is defined in latex.tex, where under the heading THEOREM ENVIRONMENTS are defined (the only macros in this section containing \it) \def\@begintheorem#1#2{\it \trivlist \item[\hskip \labelsep{\bf #1\ #2}]} \def\@opargbegintheorem#1#2#3{\it \trivlist \item[\hskip \labelsep{\bf #1\ #2\ (#3)}]} redefine them without the \it and you're in business. Since these macro names contain a @ they can only be redefined in a style file. Make your own, say foo.sty, and then add it to the list in /documentstyle, e. g., \documentstyle[12pt,foo]{article} This is a good easy example of how to hack style files. Often you don't have to understand much about how LaTeX works to make the required changes. Charles Geyer Department of Statistics University of Chicago geyer@galton.uchicago.edu

I recommend the use of Frank Mittelbach's excellent set of theorem style options. They are now used even in the AMS's AMS-LaTeX package. How to get them? Well, look into one of the large servers. I'm sure that it's somewhere on ymir.claremont.edu, probably in [.tex.inputs...]. Rainer Sch"opf
