That's conventional laziness on my part, as it is usually what I want, though it would be detrimental in this case. And I always use /o unless I'm intentionally interpolating in my pattern. Perhaps the regex engine is smart enough these days to infer that from the pattern, but it's another piece of conventional laziness. I think it's easier to read this: my $win32 = $^O =~ /Win32/i; my $path_elem = $ENV{CLEARCASE_PN}; $path_elem =~ s/ /\ /g if not $win32; Sure. It's a choice. But s/(\s)/\$1/g will handle other whitespace, too. PS: Top-posting is something we try to avoid in these lists. Sorry.  Understood. R. -- *** Richard A.
