Hi, I was converting some of my old docs from LaTeX to ConTeXt and noticed that the macro \@ is not defined in ConTeXt. latex.ltx defines it as \def\@{\spacefactor\@m} with \mathchardef\@m=1000 In LaTeX manuals it is recommended to use \@ to control the spacing after a period. For example, if you write Carrots are good for your eyes since they contain Vitamin A. Have you seen any rabbits wearing glasses? TeX considers the period (.) terminates an abbreviation and uses inter-word space rather than inter-sentence space. In LaTeX, it is recommened that one writes this as Carrots are good for your eyes since they contain Vitamin A\@. Have you seen any rabbits wearing glasses? What is the usual way of doing the same in ConTeXt? Aditya
