5.6? (weeps) well, that'll never happen. I'll have to recode with *GLOBS. (weeps some more) Thanks for all the replies. Greg

This allows the constructs such as open(my $fh, ...) and open(local $fh,...) to be used to create filehandles that will conveniently be closed automatically when the scope ends, provided there are no other references to them. This largely eliminates the need for typeglobs when opening filehandles that must be passed around, as in the following example: sub myopen { open my $fh, "@_" or die "Can't open '@_': $!"; return $fh; } { my $f = myopen("</etc/motd"); print <$f>; # $f implicitly closed here } </QUOTE> 5.6.0 also added 3-arg open($fh, $mode, $filename) for better safety against "injection" etc. Which means 5.5.x was the version that couldn't. -=- Bill Not speaking for the Firm. _______________________________________________ Boston-pm mailing list Boston-pm@mail.pm.org http://mail.pm.org/mailman/listinfo/boston-pm
