The ways to dereference a hash are

%$ref
# treat $ref as

Yes, that dereferences the hash. It's useful notation in loops...
foreach (keys %{$rHash})

Hello,
Assuming I have reference to an hash array $rHash, what would be the
way to dereference it.
Would it be: %hashEntry = %{$rHash}; ?

Don't use -w. Use the [warnings pragma][0] instead. When you say -w
you turn on warnings for everything, even modules that are not
expecting them. Read more in [perldoc perllexwarn][1].
And that is why I prefer -w.

Thank you, Bob & others. I think I now understand better. I have the
source code. So now I should be able to figure this out.

Folks,
I am reusing a code for some enhancements. According to my
understanding, it is a record with
some unique string as key and then hash array as the value.
I iterate through the array and print as follows:
foreach my $key (keys %{$abc})
{
print "$key ${$abc}{$key} \n";
}
I get values suc

Awesome, While I have been reading and writing perl for a few years

You are resetting (clearing) @EXPORT_OK. Either you need to set it all at once or push
to it (though I don't know if this latter works, should). See inline.

I do not understand what I am doing wrong. I can pass an hash this way and
not an array using the following:
require Exporter;
our @ISA = qw(Exporter);
our @EXPORT = qw();
our @EXPORT_OK = qw( @T_AREA );
our @EXPORT_OK = qw( %T_IDS );
where
@T_AREA = ( "", "NORTH", "SOUT
Can someone help me with this?
I have a query in a database that queries the columns
from the SYSCAT.COLUMNS table of either Oracle or DB2.
I want to be able to print the columns in a string as
follows:
Col1, col2, col3...etc.
depending on the table.
How would I do this?
