# \Needspace inside \multline [closed]

How to make \Needspace work inside \multline? \displaybreak would be ok, but it doesn't support arbitrary lengths.

For example:

\documentclass{article}
\usepackage{amsmath}
\usepackage{needspace}

\begin{document}
\begin{multline}
a\\
b\\
c\\
d\\
%e\Needspace{10cm}\\   % this doesn't work
f\\
g\\
h\\
i
\end{multline}
\end{document}

Why not just use the \needspace{} before the multiline? – Peter Grill Jun 26 '12 at 1:10
@Peter. Because it will produce unwanted result. – Ivan Bychkov Jun 26 '12 at 11:22
Only second part of equations should go to the second page. – Ivan Bychkov Jun 26 '12 at 11:31
Use \displaybreak[4] where you want the display is split. Defer these kind of adjustments to the final revision of the document, when you'll know that the text is in final form. – egreg Jun 27 '12 at 12:25
That's not a deal. The document must be built correctly in all cases. I'm sure Latex provides the possibility to insert conditional \displaybreak[4]. Ultimately, it provides the possibility to insert conditional \pagebreak. Why can't this be conditional \displaybreak[4]`? – Ivan Bychkov Jun 27 '12 at 14:50
