I have found the source code within octavo.dtx
(from the octavo
package) and it has some parts called \p@
. I have searched throughout the document, but cannot understand what this is defined as or what it does and it is too short a term to do a Web search. Is this specific to the document or common to TeX? Here is a portion of the code:
\if@titlepage
\newcommand\maketitle{\begin{titlepage}%
\let\footnotesize\small
\let\footnoterule\relax
\let\footnote\thanks
% \end{macrocode}
% The title itself is centered vertically, with a little offset brought by
% a |\vskip|.
% \begin{macrocode}
\null\vfil
\vskip 60\p@
% \end{macrocode}
- What does the
\p@
do?

This is abbreviated notation for a
1pt
dimension, as included inlatex.ltx
(originally inplain.tex
) and therefore common to all LaTeX documents:As such, you can use it in calculation with dimensions, such that
60\p@
translates to60
times1pt
, or60pt
. In a similar fashion,\z@
provides a0pt
dimension.Using
yields
indicating that it is a TeX dimension (number 11). Consequently, issuing
\showthe\p@
yields1.0pt
in your.log
.
