1 The Asian Journal of TEX, Volume 1, No. 1, April 2007 Article revision 2007/03/02 KTS THE KOREAN TEX SOCIETY SINCE 2007 LATEX Dissection of LATEX Macros Related to Boxes Jin-Hwan Cho ABSTRACT Boxes and glue are the key to understand how TEX makes complicated pages from individual characters and figures. Character boxes are put together into line boxes horizontally, and the line boxes are stacked vertically into paragraph boxes which finally compose page boxes. We analyze how LATEX macro commands related to boxes are composed of TEX primitives, and how the commands function. A few examples are prepared to show characteristics of the commands, and to focus the points to which ordinary LATEX users pay attention. The paper will be useful for LATEX users not only to make better LATEX documents but also to write their own style files. 1 TEX 1. TEX. TEX.,.. TEX.,. TEX (primitive). (macro) (format).
