An array is basically a list of variables. In his code above, he created it with "VAR ARRAY[5]" meaning its a list of 5 variables. You can access any one by writing ARRAY[n]. To set one you might say ARRAY[3] = 2. This would set variable at index 3 to a value of 2. Keep in mind that the indices start at 0 though. So n can be any number in the range of 0-4 in this case to access your 5 variables.
