Please help me! I can't figure it out. When I define -------------- \newenvironment{teq}{\begin{equation}}{\end{equation}} \begin{teq} x^2 + y^2 = c^2, \end{teq} To get the correct generalisation of the rule as presented in the previous chapter, we must set -------------- the line following this displayed equation is indented by a space. In this specific case, the output of dvitty is -------------- x2 +y2= c2; (1) To get the correct generalisation of the rule as presented in the previous chapter, we must set -------------- This looks like a bug in \newenvironment, or is this a feature of one of those wonderful LaTeX commands?

This behaviour is the same for every LaTeX environment, except for a few special ones (like equation) that explicitly discard spaces following their \end tag. [Classified information: this is done by setting a global switch to true, with the name of `@ignore'. The \end command checks that switch and calls TeX's \ignorespaces primitive, if necessary.] Rainer Sch\"opf
