The terminology you are looking for is multidimensional array. I.e you have
an array wherin each element is an array (actually a reference to an
anonymous array IIRC), not a scalar.
You can find the size of the array by asking for it in a scalar context, not
a list context.
For example
my @array = qw(one two three four);
my $arraysize = @array;
print "Array is $arraysize elements in length";
for a multidiemensional array
my @array = (["one", "two", "three"], ["four", "five", "six", "seven"]);
my $arraysize = @{$array[0]};
# Here you are dereferencing the array referenced by $array[0]
into an anonymous array which is the enclosing @{}, then taking the scalar
value of it which gives you the number of elements in the second level of
the array
print "First sub array size is $arraysize elements\n";
my $arraysize = @{$array[1]};
print "Second sub array size is $arraysize elements\n";

Subject: Size of Array
Thank-you to everyone who answered my last question. As usually I am very
grateful for this group and the people in it.
Quick one.. is there a way to evaluate the size of an array? Right now I'm
writing the arrays to a file and then doing an "ls -l" to compare sizes. The
array is of type $array[0][0] and not $array[0] (if anyone has the proper
terminology on this, I'd appreciate it).
Thanks,
Agustin Rivera
