My advice is to take mr vinks advice and use a file. If you insist on using a definition then you could do something like this;
global lottery as integer[17,12]
lottery[ 0 ] = [43, 76, 12, 34, 12, 11, 43, 76, 12, 34, 12, 11]
lottery[ 1 ] = [43, 76, 12, 34, 12, 11, 43, 76, 12, 34, 12, 11]
..
..
lottery[17] = [43, 76, 12, 34, 12, 11, 43, 76, 12, 34, 12, 11]
Some things to watch out for;
DO NOT USE DIM Read this

You need to download and install Version 2.0.18 or it will not work
All arrays begin with index zero. When you define an array, say arr[10], the 10 refers to the LAST element not the number of elements
AGK will reduce the length of your array to the number of elements you define
