"Can't use an undefined value as an ARRAY reference at .."
This means that it isn't an array ref, so there must be a problem elsewhere
in your code. You can verify this by using Data::Dumper to print out some
debugging info.
use Data::Dumper;
print Dumper $::alpha{'a'}{'b'};
This will print the entire structure under 'b'. So verify that 'b' is a
hashref with a key named 'c', and that 'c' is an arrayref.
If you need to force 'c' to be an arrayref you can do this...
unless ( ref $::alpha{'a'}{'b'}{'c'} eq 'ARRAY' ) {
# not an array ref, so make it one!
$::alpha{'a'}{'b'}{'c'} = [];
}
....Or you could use similar code to issue a warning if it is not an
arrayref, like this...
unless ( ref $::alpha{'a'}{'b'}{'c'} eq 'ARRAY' ) {
die "Error! Not an array ref!";
}

Subject: question regarding hash hash hash array
Hi ,
I have declared a hash hash hash array as
$::alpha{'a'}{'b'}{'c'}=['p','q','r'];
and when I do to put these in a local variable array as
@::my_array=@{$::alpha{'a'}{'b'}{'c'} };
I get the values of the array when i use it in my test script, when when I
include this in my main code i get the following error
" Can't use an undefined value as an ARRAY reference at .."
Any help is appriciated and thanks in advance ...
