Re: Dynamically Building Variable Names

No, you probably don't want that. You want a real data structure, possibly a hash of hashes of arrays by your description.

my $data = {
            example => {
                         other => [ ],
                       }
           };
$data->{example}->{other}->[0] = "wuzzle";

Or, just to keep it simple, and more like what was requested originally (as there may be something else that we don't know about, that would have problems if it were a deep structure), you can use a flat hash: `my %data; $data{'exampleother1'} = 'something'; $data{'exampleother2'} = 'something else'; $data{$var1.$var2.$number} = $value; # or using a hashref my $data; $data->{'exampleother1'} = 'something'; $data->{'exampleother2'} = 'something else'; $data->{$var1.$var2.$number} = $value;` [download] The deeper structure has advantages if you might have values for ($var1.$var2) that collide. (if those should be two discrete values, then use a hash of hashes or some other complex structure. If they should be the same value, then just use a single dimensional hash).	[reply] [d/l]

my %data;
$data{'exampleother1'} = 'something';
$data{'exampleother2'} = 'something else';
$data{$var1.$var2.$number} = $value;

# or using a hashref
my $data;
$data->{'exampleother1'} = 'something';
$data->{'exampleother2'} = 'something else';
$data->{$var1.$var2.$number} = $value;
