You're almost there. I'd try something like this: open( $nbdc_filehandles[$index], $filename) or die $!. But $nbdc_filehandles[$index] = \*FILE should work also. I always have trouble reading from an array index though. There's probably a better way to do it, but I end up using my $scalar = $a[0]; my $line = <$scalar>

UPDATE: perlapio always turns out to be a much stranger animal than I ever think. It appears that you can push either \*FILE or *FILE and both work just fine (even though they are different) inside the <>'s — which don't appear to be operators the way I'm used to thinking of them.

use strict;

my $f;
my $l;
my @a = ();

open FILE, "/etc/passwd" or die $!;
push @a, \*FILE;
$f = $a[0];
$l = <$f>;
print $l;

open FILE, "/etc/passwd" or die $!;
push @a, *FILE;
$f = $a[1];
$l = <$f>;
print $l;

open $a[2], "/etc/passwd" or die $!;
$f = $a[2];
$l = <$f>;
print $l;

use Data::Dumper; $Data::Dumper::Indent = $Data::Dumper::Sortkeys = 1;
print "", Dumper(\@a), "\n";

See? $a[0] and $a[1] are indeed different. I guess I'm OK with the fact that they both work inside the <>'s but what part of speech is <>? Is that a lexical shortcut to IO::Handle's getline()? I'm sure I figured this out before.

Also, is there a way to read from $a[1] without first setting $f = $a[1]?
