50 20 Sectioning commands20 Sectioning commands\section@numYou use \beginnumbering and \endnumbering to begin and end a line-numberedsection of the text; the pair of commands may be used as many times as youlike within one document to start and end multiple, separately line-numberedsections. LaTeX will maintain and display a ‘section number’ as a count named\section@num that counts how many \beginnumbering and \resumenumberingcommands have appeared; it needn’t be related to the logical divisions of yourtext.\extensionchars\ifnumbering\numberingtrue\numberingfalse\ifnumberingR\ifl@dpairing\l@dpairingtrue\l@dpairingfalse\ifpst@rtedL\pst@rtedLtrue\pst@rtedLfalse\l@dnumpstartsL\ifledRcol\ifledRcol@Each section will read and write an associated ‘line-list file’, containing informationused to do the numbering; the file will be called 〈jobname〉.nn, where nn is thesection number. However, you may direct that an extra string be added before thenn in that filename, in order to distinguish these temporary files from others: thatstring is called \extensionchars. Initially it’s empty, since different operatingsystems have greatly varying ideas about what characters are permitted in filenames. So \renewcommand{\extensionchars}{-} gives temporary files calledjobname.-1, jobname.-2, etc.163 \newcount\section@num164 \section@num=0165 \let\extensionchars=\emptyThe \ifnumbering flag is set to true if we’re within a numbered section (that is,between \beginnumbering and \endnumbering). You can use \ifnumbering inyour own code to check whether you’re in a numbered section, but don’t changethe flag’s value.166 \newif\ifnumberingIn preparation for the eledpar package, these are related to the ‘left’ text of paralleltexts (when \ifl@dpairing is TRUE). They are explained in the eledpar manual.167 \newif\ifl@dpairing168 \l@dpairingfalse169 \newif\ifpst@rtedL170 \pst@rtedLfalse171 \newcount\l@dnumpstartsL\ifledRcol is set to true in the Rightside environnement.
