What are for example the star versions of the internal macros \flalign
and \endflalign
?
1 Answer
The question isn't that clear but the definitions of flalign
and flalign*
are
\newenvironment{flalign}{%
\start@align\tw@\st@rredfalse\m@ne
}{%
\endalign
}
\newenvironment{flalign*}{%
\start@align\tw@\st@rredtrue\m@ne
}{%
\endalign
}
So they are the same except that \ifst@rred
is true in the star form (and mostly they are the same as align
).
That switch is tested at various points in the code for (fl)align(*)
typically with lines like
\ifst@rred\else\global\@eqnswtrue\fi
If you mean what is the macro that holds the top level definition, in the way that \flalign
holds the definition of \begin{flalign}
then that is \flalign*
but you can only type it that way if you do \catcode\`\*=11
to make *
a letter so normally it would be accessed via
\csname flalign*\endcsname

Thanks a lot. Why do I forget to use csname ? A big mystery... :-) Jun 11, 2020 at 21:55
figure*
environment in a one or two column environment.\end{...}
so you can not use the\foo...\endfoo
form, you have o use an environment.
