Multi dimensional array

Hi Adil,

You can do this easily with a table:

data=makeTable('myData 0) ; the 0 is the default value you want to return

data[list(3 2)]=45
data[list(5 6)]=123

Because the table can have anything you want as the key, passing a list of an X and Y value is perfectly acceptable. Derek mentioned this in his post.

Or you could create a multi-dimensional array very simply by using SKILL as follows. Essentially SKILL supports simple (single dimension) arrays, but it's easy to create an array which is an array of arrays).

Function for creating a multi-dimensional array.

Usage:

data=abMultiDimArray(6 8)

Creates a 6 by 8 array (starting index is from 0). Then you can use:

data[4][5]=23
data[0][7]=123

You can specify more dimensions by passing more arguments to abMultiDimArray.
