I am not sure that 'cm' or other unit designations have to do with conventional or other algebraic notation, but if they do, and if you draw parallels with J, what in J corresponds to 'cm'? Also, what is 'the J convention for omitting parentheses' and how is it 'better'? ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
