I'm having some trouble using a hash of arrays. I thought I was starting
to understand the jumbled mass of variable use in Perl, but perhaps not...
Instead of the missing switch() statement, I'm using a hash set up like
this:
%zone_info = (
'EST' => [5,'EST', 4,'EDT'],
'EST5' => [5,'EST-'],
'CST' => [6,'CST', 5,'CDT'],
'MST' => [7,'MST', 6,'MDT'],
'MST6' => [6,'MST-'],
'PST' => [8,'PST', 7,'PDT'],
'AKST' => [9,'AKST',8,'AKDT'],
'AST' => [4,'AST'],
'HST' => [10,'HST']
);
I can get values from deep inside it's bowels by a statement like:
print $zone_info{'EST'}[3];
That gets repetitive, so I'd like to simplify it this way:
@[EMAIL PROTECTED]'EST'};
print $info[3];
...but that doesn't work! Nothing prints. What am I doing wrong?
You're not using the array reference in zone_info correctly.
my $info = $zone_info{'EST'};
print $info->[3];
thanks much,

You're welcome.
