you can use the .length attribute of any array to change the size based on variables
consider this code
score as integer [ 2, 3 ]
score.length = 4 // makes the array [4,2]
score[2].length = score.length // makes the 3rd row have 4 members so this array is no longer a square array!
print(score.length) // gives 4
print(score[2].length) // gives 4
print(score[1].length) // gives 3 as this one hasnt been resized yet
and this code to resize the whole array
score.length = new_x_value
for i = 1 to score.length
score [ i ].length = new_y_value
next i
also checkout the .insert command too that can be used on arrays
