I'm a fairly new perl user, so excuse me if this is a dumb question.

I know I can change my working directory with chdir(<string>).  Is there a 
symmetrical operation which tells me what my working directory is (short
of invoking pwd in a subshell, that is)?  Imagine my surprise when I
found out that chdir() doesn't set $ENV{'PWD'} !  Do I really have to
test each chdir() for success and then conditionally assign its argument
to $ENV{'PWD'} ?  The programs I'm invoking after the chdir() expect
$PWD to be accurate.
