thanks Terry and others,

brings me to one other question:
I guess this function is only evaluated once, is that correct ?

about os.curdir,
I checked it, it's already a constant ;-)
and because I use afterwards:
os.path.abspath ('.'')
which is identical to
os.path.getcwd( )

about '.' being the current directory,
well I think windows was thrown at the market about 25 years ago,
and since then we don't use '.' anymore ;-)

cheers,
Stef

No, even Windows uses '.' as the current directory -- at least XP does, I
haven't tried Vista.

However, old Classic Mac OS (pre OS-X) used ':' for the current
directory, so dot isn't universal.
