Sometimes, it is convenient if I know I am in frontmatter or bodymatter.  when desinging a book, we make a new chapter open at a right page and design the header to show the chapter title and pagenumber. We have to set the pagenumber at the page where a chapter title is located. \definetext  [chapterstart]  [footer]  [{\hfill\bf\pagenumber\hfill}]\setuphead  [chapter]  [footer=chapterstart] if this book consists of a frontmatter and a backmatter, I have to set the text for the titles in frontmatter and chapters in bodymatter like this, for roman pagenumber in frontmatter. \startsectionblockenvironment[frontpart]  \definetext    [titlestart]    [footer]    [{\hfill\bf\romannumerals\pagenumber\hfill}]  \setuphead    [title]    [footer=titlestart]\stopsectionblockenvironment \startsectionblockenvironment[bodypart]  \definetext    [chapterstart]    [footer]    [{\hfill\bf\pagenumber\hfill}]  \setuphead    [chapter]     [footer=chapterstart]\stopsectionblockenvironment  so, is there a command to make me know if I am in frontmatter or bodymatter? if so, I can use only one command to achieve that setup \definetext  [chapterstart]  [footer]  [{\hfill\bf\ifinfrontmatter ... \else ... \fi\hfill}]  regards, Tim
