	Korn Shell keeps the current directory in a variable $PWD,
	which is updated every time you change directory.
	In the current and current-1 versions of ksh, if the PS1
	variable contains a shell variable, it will be evaluated every
	time PS1 is displayed as a prompt.  The trick is to set
		PS1='$PWD '	## note single quotes
	so PS1 contains the string $PWD, not the value $PWD had when
	you set it (which you get with PS1="$PWD ".)  You can also use
	this with other shell variables, such as $? and $SECONDS.
