console '# ' with {PWD} ??

Hi people...

i recently installed AIX 5.3 on a server...
but now when i login with root it only shows '# ' without the location where i am...
for example: if im in /usr/local
it continues to show only '# '
and i want to see the path like 'root@server:/usr/local#'

someone can help me?
thanks

So that all users may have this comfort:

root@sremhv27:/etc> grep PS1 profile
PS1='"$LOGNAME@$NODE:$PWD> "'
export PS1

add this in your .profile file then logout and and login
export PS1='$LOGNAME-$PWD>'
or
export PS1="`tput smso`$LOGNAME@`hostname``tput rmso`-"'$PWD> '
