This works
Foreach ( @{$hash{$key1}{$key2}} )
This does note
Foreach ( @{($hash{$key1}{$key2})[9..1]} )
This gives me this error
Can't use undefined value as an array reference.
TIA,
Paul Kraus

It should be:
foreach ( @{ $hash{$key1}{$key2} }[1 .. 10] ) { ... }
based on your other email.

This worked fine. However I was under the impression that any time you
worked with a slice that you had to surround the array in parenthesis.
When else does this not apply?

Hi All,
My data structure is a hash of a hash of an array. I build it from an
input file by the following code. Could you help me write it back to an
output file, please?
# Code Begins
%data = ( );
open (IN, in.txt) || die;
while (IN) {
chop;
($user_name, $file_name, $modified_by
