This is reason why we cannot use paragraph mode where each resulting box has the width `\hsize`. The `` is set active and `\everypar` starts `\hbox{` and acive closes this `\hbox` by `}`. \_cod ----------------------------- \_def\_boxlines{% \_def\_boxlinesE{\_ifhmode\_egroup\_empty\_fi}% \_def\_nl{\_boxlinesE}% \_bgroup \_lccode`\~=`\^^M\_lowercase{\_egroup\_let~}\_boxlinesE \_everypar{\_setbox0=\_lastbox\_endgraf \_hbox\_bgroup \_catcode`\^^M=13 \_let\_par=\_nl \_aftergroup\_boxlinesC}% } \_def\_boxlinesC{\_futurelet\_next\_boxlinesD} \_def\_boxlinesD{\_ifx\_next\_empty\_else\_ea\_egroup\_fi} \_public \boxlines ; \_doc ----------------------------- The \`\report` style initialization macro is defined here. \_cod ----------------------------- \_def\_report{ \_typosize[11/13.2] \_vsize=\_dimexpr \_topskip + 52\_baselineskip \_relax % added 2020-03-28 \_let\_titfont=\_chapfont \_titskip=3ex \_eoldef\_author##1{\_removelastskip\_bigskip {\_leftskip=0pt plus1fill \_rightskip=\_leftskip \_it \_noindent ##1\_par}\_nobreak\_bigskip } \_public \author ; \_parindent=1.2em \_iindent=\_parindent \_ttindent=\_parindent \_footline={\_global\_footline={\_hss\_rmfixed\_folio\_hss}} } \_doc ----------------------------- The \`\letter` style initialization macro is defined here.
