OK, here we go. The following is a .sty file for ACM proceedings. I picked it up from somebody (don't remember whom just now, so sorry I can't give proper acknowledgements) and added a few hacks of my own, most noteably adaption to A4 output and another style of headers, closer to ACM guidelines. It would be nice if somebody added a mechanism to automatically convert all section headers to upper case only, as required by ACM guidelines. I kludged around for a while with \uppercase myself and never got it to work properly, but surely there are more experienced LaTeX hackers out there than me. And yes, I take no responsibility whatsoever for the possible consequences etc. of using this piece of software...

In article <1990Sep7.092931.1958@sics.se>, bjornl@sics.se (Bj|rn Lisper) sends a copy of an old "ACM document style" done by Leslie Lamport. This style is nothing at all like the style that the ACM, in its written requirements, asks for. Enclosed below is a style file I did that provides a pretty good match to the published ACM requirements. I was in touch with someone at the ACM at one point about having this (or something like it) distributed as the "standard" for camera-ready ACM reports; however, nothing seems to have come of that. This style produces a ready-to-go document at 9pt. (Hey, I didn't choose the sizes; the ACM did.) This turns out to require that you generate a font (a bold-faced san serif 9pt) that is not in any of the standard distributions. See the comment in the "FONTS" section of the style file. An alternative which I considered, but don't have the code for, is to magnify everything to a 10pt base font and then photographically reduce it by 10%. This has two advantages: No non-standard fonts are required, and the result- ing documents should look somewhat better (as they'll have a higher effective resolution.) The magnified document will fit on standard 8.5 x 11 paper with workable margins. (This is not the case if you try and magnify to an 11pt base font.) The downside, of course, is that it requires that whoever you send the document to be able and willing to do the photographic reduction. I don't know whether the ACM is - I suggested it to them but heard nothing back.

Works like TeX's % \firstmark command. % The marking commands work reasonably well for right marks 'numbered % within' left marks--e.g., the left mark is changed by a \section command and % the right mark is changed by a \subsection command. However, it does % produce somewhat anomalous results if two \bothmark's occur on the same page. % % Commands like \tableofcontents that should set the marks in some page styles % use a \@mkboth command, which is \let by the pagestyle command (\ps@...) % to \markboth for setting the heading or \@gobbletwo to do nothing. \mark{{}{}} % Initializes TeX's marks % \ps@empty and \ps@plain defined in LATEX.TEX % % In this style, none of the headings are meaningful; we turn them all into % "empty". % \let\ps@headings=\ps@empty \let\ps@myheadings=\ps@empty \let\ps@plain=\ps@empty % **************************************** % * MISCELLANEOUS * % **************************************** % % DATE % \def\today{\ifcase\month\or January\or February\or March\or April\or May\or June\or July\or August\or September\or October\or November\or December\fi \space\number\day, \number\year} % **************************************** % * INITIALIZATION * % **************************************** % % Default initializations.
