Re: New line not working for latex math mode?

I've only tried one line break, not two and not subsequent:
>> set label "a \n b" at 0,90
>> set label 'a \\ b' at 0,70
>> set label "a \\\\ b" at 0,60

and anyway, I'd say these commands do not generate equations.

I haven't tried something like that but, I guess I would have to
replace \cr with something like \\ which is not working, anyway.

Some of my attempts weren't equations, and they weren't working, anyway:
>> set label "a \n b" at 0,90
>> set label 'a \\ b' at 0,70
>> set label "a \\\\ b" at 0,60

I agree. Compiling the following with pdflatex works fine (places "a"
and "b" in different lines):

\documentclass[english]{article}
\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}
\usepackage{babel}
\begin{document}
a \\ b
\end{document}


Thanks
