I then gave some examples where I had felt it necessary to rewrite internal LaTeX code. The examples dated from about 1989. I now realize that I could have accomplished all those things by \letting \@chapter (for example) be \@@chapter, then defining \@chapter to be {some code}\@@chapter{some code}. I don't believe I was familiar with that trick 5 years ago, but I have used it several times recently. This probably means that although an \everychapter, \everysection, etc, would be _nice_, they probably are not _necessary_. -- Charles Wells Department of Mathematics, Case Western Reserve University 10900 Euclid Avenue, Cleveland, OH 44106-7058, USA 216 368 2893
