array of arrays

I saw mention of
New array of arrays (of arrays etc...).
in versions.txt but couldn't find any docs on it.

it doesn't look like you can do an auto array of array ie:
local a[] = [[1,2],[3,4,5],[1,2]]

How is it used?

I couldn't get your example to work, but if you use the 'Array' type it works. There's a catch though: All the elements and subelements have to be the same type. Example:

Foo:Array = [[1, 2, 3], [1, 2, 3]] 'OK!
Foo:Array = [["A", "B", "C"], [1, 2, 3]] 'Not OK

It's an array of an array, so the syntax would be:

Local a[][] = [ [1,2], [3,4,5], [1,2] ]

if that's the case, how are the inner arrays accessed?

By indexing the outer array!



a[][] is an array of arrays.

a1[] is each array in a[][]

a2 is each int in a1[]

You can also use standard BASIC multidimensional arrays, but the [exp,exp...] syntax only works with 1 dimsenional arrays. And yes, an array of arrays is a one dimensional array.

a[ 0 ] = [ 1, 2 ]
a[ 1 ] = [ 3, 4, 5 ]
a[ 2 ] = [ 1, 2 ]

Therefore

a[ 0 ][ 0 ] = 1

Etc.

couldn't figure out the syntax... I didn't think of putting the brackets in the first "For" loop. makes sense though. Great addition to Blitz!
