array_height_2d(array);
| Argument | Description |

| array | The array to check. |
Returns: Real
With this function you can get the height (number of entries) of
a the first dimension of a 2D array. You supply the array to check
and the output from the function tells you how many initial entries
it contains. You can get the number of entries for the second
dimension of the array using the function array_length_2d.
for (var i = array_height_2d(a); i > -1;
i--;)
{
for (var j = array_length_2d(a, i); j > -1;
i--;)
{
a[i, j] = -1;
}
}
The above code will loop through a 2D array and set each entry to -1.
