We just got a few ideas sent to us for the changing of PS1 to
show the current directory that you are on (/usr/lib$... etc...) but
have in the process managed to discover a few problems with our
Xenix system.  We are trying to get this to work before we go over
to the Sperry 5000/80's at the end of December.

We are running Xenix Revision 3.4 from Intel and the Bourne shell
won't let us do things like the following...

	export ps1
	cd()
	{
		builtin cd $* &&
		case "$1" in
		"")	PS1="$ps1" dir=$HOME ;;
		/*)	PS1="`basename $1`$ps1" dir=$1 ;;
		..|*/..)	dir=`/bin/pwd`; PS1="`basename $dir`$ps1" ;;
		*/*)	PS1="`basename $1`$ps1" dir= ;;
		*)	PS1="$1$ps1" dir= ;;
		esac &&
		export PS1
	}

The program bombs at the cd() statment and returns the statment:
-sh: syntax error: `(' unexpected

Any ideas on whats wrong and what might be done in another method to
correct the problem that we seem to be having? We have tested this
on the Sperry and it seems to work, but not on the smaller Intel 310
machines.

Any help would be appreciated.
