Edward:
What you have there is an array with only one scalar element (an array
reference containing 3 values). Note that $array[1] & $array[2] would be
undefined in your example. I think what you intended was to do:
@array = ('1','2','3'); # An array containing three elements, '1', '2',
'3'
(Or more simply: @array = (1..3); )
With regards to switching between string & numeric values, perl will do
this automagically for you. You can just perform whatever math you want
as per normal. Consider the following:
@array = ( '1', '2', '3');
print $array[0] + 1;
Output: 2
Hope this helps.
