A temporarily used register.
\TagsPlusEndmarks Since amsmath uses “tags” for setting end marks, some macros are defined
which prepare tags which include endmarks:
\SetOnlyEndMark
319 \gdef\TagsPlusEndmarks{%
320 \global\let\Old@maketag@@@=\maketag@@@
321 \global\let\Old@df@tag=\df@tag
322 \if@eqnsw\SetTagPlusEndMark
323 \else
324 \iftag@\SetTagPlusEndMark
325 \else\SetOnlyEndMark
326 \fi
327 \fi}
Lines 320, 321: store the original macros.
Line 322: if equation numbers are set as default, call \SetTagPlusEndMark
to set tag and end mark.
Lines 323, 324: if a tag is set manually, call \SetTagPlusEndMark to set tag
and end mark.
Line 325: otherwise, call \SetOnlyEndMark to set only an end mark.
328 \gdef\SetOnlyEndMark{%
329 \global\tag@true
330 \iftagsleft@
331 \gdef\df@tag{\hbox
332 to \displaywidth{\hss\PotEndMark{\maketag@@@}}}%
333 \else
334 \gdef\df@tag{\PotEndMark{\maketag@@@}[\ifhmode\else\hbox to .1pt{}\fi]}%
335 \fi}
Set only an end mark:
Line 329: force setting the end mark as a tag:
Lines 331, 332: if tags are set to the left, the tag consists of a \hbox over the
whole displaywidth, with the (potential) endmark at its right.
Line 334: if tags are set to the right, the tag consists only of the (potential)
endmark. If no endmark is set and TEX is not in hmode, an
empty hbox is output (otherwise \abovedisplayskip will be ignored
