Here's a couple I wrote for the 5R2 Bourne Shell:
I don't set the prompt to the directory names because I find it
disgusting, but you can do that by doing PS1="$DIRSTACK" in both
popd and pushd.

which() {
   whatis $*
}

pushd()  {
    if cd $1
    then
        DIRSTACK="$1 $DIRSTACK"
        echo $DIRSTACK
    fi
}
popd()  {
    set $DIRSTACK
    shift
    DIRSTACK="$*"
    if test "$1" = "" 
    then
	echo $HOME
    else
        echo $DIRSTACK
    fi
    cd $1
}
