In newer perl's you can store a filehandle directly to a lexical variable. This should allow you to do what you need. my $FILEHANDLE; open $FILEHANDLE, '/tmp/file/to/open' or die "Can't open file: $!"; Obviously the variable will need to be scoped to the subroutine. Though it seems a bit odd that you want to recursively read a filehandle. http://danconia.org -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
