If the optional \meta{within} argument is given the the counter `\meta{ctr}' is reset to zero each time the counter `\meta{within}' changes. The command \cmd{\the\meta{ctr}} typesets the value of the counter \meta{ctr}. This is automatically defined by \cmd{\newcounter} and is initialised to typeset arabic numerals. \ml{\cmd{\counterwithin}\\\cmd{\counterwithin*}} It is sometimes desireable to change a counter that has been defined by \cmd{\newcounter}\marg{ctr} to act as though it had been defined as \cmd{\newcounter}\marg{ctr}\oarg{within}. The package provides the command \cmd{\counterwithin}\marg{ctr}\marg{within} that accomplishes this. By default, it also redefines the \cmd{\the\meta{ctr}} command so that it typesets values in the style \texttt{\cmd{\the\meta{within}}.\cmd{\arabic}\marg{ctr}}. The starred version of the command suppresses the redefinition of \cmd{\the\meta{ctr}} (e.\,g., \cmd{\counter\-within*}\verb+{ctr}{within}+). \ml{\cmd{\counterwithout}\\\cmd{\counterwithout*}} Likewise, the command \cmd{\counterwithout}\marg{ctr}\marg{within} changes a counter that has been created by \cmd{\newcounter}\marg{ctr}\oarg{within} to act as though it had been created by \cmd{\newcounter}\marg{ctr}. By default it also redefines the \cmd{\the\meta{ctr}} command so that it just typesets an arabic numeral. The starred version of the command suppresses the redefinition of \cmd{\the\meta{ctr}}. Any number of \cmd{\counterwithin}\marg{ctr}\marg{\ldots} and \cmd{\counterwith\-out}\marg{ctr}\marg{\ldots} commands can be issued for a given counter, \meta{ctr}, if you wish to toggle between the two styles. The current value of \meta{ctr} is unaffected by \cmd{\counterwithin} and \cmd{\counterwithout}. If you want to change the value after one of these commands, use \cmd{\set\-counter}\marg{ctr}\marg{\ldots}, and to change the typeseting style use \cmd{\renew\-command}\texttt{\{}\cmd{\the\meta{ctr}}\texttt{\}}\marg{\ldots}. \section{Change History:} \begin{tabular}{@{}l@{ -- }l@{}} v1.0a & New maintainer (Will Robertson)\\ v1.1a & The package commands are now defined in the format \end{tabular} \end{document}
