Hi, I have two separate issues here. First, I'm struggling to get math cases to work. The wiki suggests that the following code \starttext \startformula f(x) = \startmathcases \NC x, \NC if $0 \le x \le \frac12$ \NR \NC 1-x ,\NC if $\frac12 \le x \le 1$ \NR \stopmathcases \stopformula \stoptext should typeset everything after the \NC in text mode, but when I compile it's still in math mode. Is this a bug or is the wiki out of date? Secondly, how can I enter text mode whilst in a formula, whilst also only using the roman font? For example, I would like it so that even if the whole text is wrapped in {\em ...}, the text in the formulae are in roman font. I've tried the following: \starttext {\em \startformula \startalign[align=left] \NC {\rm multiple words of text} \NR % Does not provide spacing \NC \mathrm{multiple words of text} \NR % Does not provide spacing \NC \text{multiple words of text} \NR % Still italicised % \NC \text{\rm multiple words of text} \NR % Error % \NC {\rm \text{multiple words of text}} \NR % Error \stopalign \stopformula } \stoptext Thanks, Jack
