It removes the \ifinedef primitive for a different primitive, namely \currentexpansionmode. This read-only register is 0 when doing regular typesetting, 1 when inside \edef or \xdef and 2 in other cases of full expansion with scan_toks. It could possibly be extended to distinguish between \marks and \write etc. Comments more than welcome on this one! I have also added an \ifalignscanning test. It is true whenever TeX is looking for \noalign etc. so is most useful for a \stopalignscanning function defined as \def\stopalignscanning{\ifalignscanning\relax\fi} ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=495&aid=469&group_id=106
