[Tugindia] Numbering in enumerate

[Manoj Kummini]

Hello Kapil,

Let me elaborate my question. When one uses \label{key} in a LaTeX
document, an entry of the form
\newlabel{key}{{\@currentlabel}{\thepage}}
is made in \jobname.aux. When \label is used inside the enumerate
environment, \@currentlabel takes the value \p@enumxxx\theenumxxx,
where xxx denotes the current \@enumdepth. \p@enumxxx is a recursive
definition that determines the prefix as below: if one is in an
enumerate environment of depth three, \p@enumiii will describe how
the previous two depths should be referred to, as in 1(a)i, which is
the Standard LaTeX style. In enumerate.sty, the optional argument
[(a) ] for an enumerate environment, say at depth one, sets \theenumi
as \alph{c@enumii}, without the parentheses, and, therefore, the
parentheses do not get carried over to the definition of \p@enumii,
which is not modified by enumerate.sty. This is what I understood
from reading that file; perhaps I am wrong. Because this is not
carried over to \p@enumii, the value of \@currentlabel at lower
depths do not have the parentheses, which will affect the way a
reference to an item is printed. See, e.g., the following piece of
code:

\documentclass{article}
\usepackage{enumerate}
\begin{document}           

\begin{enumerate}[(a) ]

\item\label{item1}
\begin{enumerate}[1 ]
\item \label{item11}
\makeatletter

\verb|\p@enumi|  =  \p@enumi

\verb|\p@enumii|  =  \p@enumii

\verb|\@currentlabel| =  \@currentlabel

\makeatother
\end{enumerate}
\end{enumerate}

See item \ref{item11}% \ref{item12} \ref{item2}. 

\end{document}
