chapterslyxroman numerals
When I am using the following command
\renewcommand\thechapter{\Roman{chapter}}
to set the chapter # to roman. It is also changing the subsection numbering to roman. Do you have any idea, why?
Example: It is showing the Chapter III
and then in the subsection it says
III.4.1
Please suggest a solution
Without a minimal example it's difficult to say; but
\renewcommand{\chaptername}{CHAPTER}
\renewcommand{\thechapter}{\Roman{chapter}}
should be all you need.
With memoir, there are several facilities one can exploit. Here's a solution that should accomplish your desires.
\documentclass{memoir}
\usepackage{kantlipsum} % just for the example
\makeevenfoot{headings}{}{}{\thepage}
\makeoddfoot{headings}{}{}{\thepage}
\makeevenhead{headings}{}{}{}
\makeoddhead{headings}{}{}{}
\copypagestyle{chapter}{plain} % make chapter a page style of its own
\makeevenfoot{chapter}{}{}{\thepage}
\makeoddfoot{chapter}{}{}{\thepage}
\makeevenhead{chapter}{}{}{}
\makeoddhead{chapter}{}{}{}
\renewcommand{\printchaptertitle}[1]{\chaptitlefont\MakeUppercase{#1}}
\makeatletter
\renewcommand{\printchaptername}{\chapnamefont\MakeUppercase{\@chapapp}}
\makeatother
\renewcommand{\printchapternum}{\chapnumfont\Roman{chapter}}
\begin{document}
\frontmatter
\chapter{Introduction}
\kant[1]
\mainmatter
\chapter{A title}
\section{Something}
\kant
\end{document}
I added also a chapter in the front matter to show that the style is the same.
When you define a counter, LaTeX performs two actions. It creates the actual counter by assigning it to a register, but it also creates a counter representation macro. For some counter <cntr>, the latter is given by \the<cntr>. Internally, this is handled by the macro \@definecounter (from latex.ltx, with comments added):
\def\@definecounter#1{\expandafter\newcount\csname c@#1\endcsname% <- Defined \c@<cntr>
\setcounter{#1}\z@% <------------------------------------------- Sets counter to 0
\global\expandafter\let\csname cl@#1\endcsname\@empty% <-------- Clear/reset list \cl@<cntr>
\@addtoreset{#1}{@ckpt}%
\global\expandafter\let\csname p@#1\endcsname\@empty% <--------- Reference prefix \p@<cntr>
\expandafter
\gdef\csname the#1\expandafter\endcsname\expandafter% <--------- Sets \the<cntr>
{\expandafter\@arabic\csname c@#1\endcsname}}% to be \arabic{<cntr>}
So, for your purposes, the use of
\newcounter{Abc}
LaTeX creates
\c@Abc
\theAbc
(and some other stuff). By default, \the<cntr> is set to \arabic{<cntr>}. But you can redefine that the way you want to. Specifically, in your case, use \Roman{<cntr>} and use \the<cntr> elsewhere.
\documentclass{article}
\newcounter{exampleCounter}
\renewcommand{\theexampleCounter}{\Roman{exampleCounter}}
\newenvironment*{Example}
{\refstepcounter{exampleCounter}% \begin{Example}
\par\addvspace{\topsep}%
\noindent\textbf{Example~\theexampleCounter}\par%
\itshape\ignorespaces\noindent}
{\par\addvspace{\topsep}%
\ignorespacesafterend}% \end{Example}
\begin{document}
\noindent Here is some regular text.
\begin{Example}\label{EX:BLAH}%
This is an Example, I want to reference
\end{Example}
This is a reference to Example~\ref{EX:BLAH}.
\end{document}
It's important to change \the<cntr> since that's exactly what is used when you make a \label - LaTeX stores in the label/reference the value of the last \the<cntr> that was stepped.
