is continued with \@flushglue (the actual position is one space after the
text), and then the endmark is placed (by \PotEndMark).
Handling of Endmarks
\@endtheorem-thmmarks \@endtheorem is called for every \end{〈env〉}, where 〈env〉 is a theoremlike
environment. \@endtheorem is extended to organize the placement of
the corresponding end mark (\InTheoTypegives the innermost theorem-like
environment, i.e. the one to be ended):
96 \gdef\@empty{}
97 \gdef\@endtheorem{%
98 \expandafter
99 \ifx\csname\InTheoType Symbol\endcsname\@empty\setendmarkfalse\fi
100 \@endtrivlist
101 {\ifsetendmark
102 \unskip\nobreak\hfill\nobreak\csname\InTheoType Symbol\endcsname
103 \setendmarkfalse \fi}%
104 \ifsetendmark\OrganizeTheoremSymbol\else\global\setendmarktrue\fi
105 \csname\InTheoType @postwork\endcsname
106 }
Lines 98, 99: if the end symbol of the environment 〈env〉 to be closed is
empty, simply no end symbol has to be set (it makes a difference, if
no end symbol is set, or if an empty end symbol is set).
Lines 100, 104: (originally, it calls \endtrivlist):
Lines 100, 102, 103: \@endtrivlist is called to put 〈env〉Symbol at the end
of the line and set setendmark to false if TEX is in a text line and
setendmark is true.
At this point, setendmark is false iff the user has disabled it locally or
the end symbol is empty.
Line 101: the endmark is not set, if setendmark is false.
Line 104: if setendmark is true, the correct placement of the end symbol is
organized, else (ie either setendmarkfalse is set by the user, or the endmark
is already set by \@endtrivlist) reset setendmark to true.
Forfurthercommentssee\@endtrivlistand\OrganizeTheoremSymbol.
The construction in line 102 guarantees that the endmark is put at the end
of the line, even if it is the only letter in this line.
\NoEndMark By \NoEndMark, the automatical setting of an end mark is blocked for the
current environment.
107 \gdef\NoEndMark{\global\setendmarkfalse}
set setendmark to false. It is automatically reset to true after the end of
the current environment.
