Also, note that div and rot should be in text font. You should probably do \startmathcollection[default] \definemathcommand [div] [nolop] {\mfunction{div}} \definemathcommand [rot] [nolop] {\mfunction{rot}} \stopmathcollection and use \div \rot etc. HTH, Aditya -- Aditya Mahajan, EECS Systems, University of Michigan http://www.eecs.umich.edu/~adityam || Ph: 7342624008
