2D Array within a Type

How do you create a 2D Array within a type, since you do not dimension the array as in BlitzPlus

Type Grid
Field GridNumber:Int
Field GridSector:Int
Field GridImage:TImage
End Type

The GridImage field will hold a graphic image used with a for loop to draw the grid. This should be done without the use of TLists as I will need to access an element of the GridNumber without looping through the list.

Using a normal 2D array:

Type TGrid
	Field coords:Int[10,10]
End Type

Local myGrid:TGrid = New TGrid

For Local X = 0 To 9
	For Local Y = 0 To 9
		myGrid.coords[X,Y] = X+Y
	Next
Next

For Local A = 0 To 9
	For Local B = 0 To 9
		Print myGrid.coords[A,B]
	Next
Next

Multidimensional arrays cannot be resized.
See the BlitzWiki for more info.

Can the image (that is the reference to the image) be loaded into the type field (GridImage) that is a 2D array so that the grid can be drawn using
For x = 0 to 9
For y = 0 to 9
Print myGrid.GridImage(x, y), x*32, y*32
next
next

it *could* but unless they're all unique images, you'd be better having an array of ints that refer to the images.

i.e.:

Global images:TImage[5]
for Local a = 0 to 4 
	images[a]:TImage = LoadImage("tile"+a+".png") 'load tile0.png, tile1.png, tile2.png etc
Next
Type TGrid
	Field coords:Int[10,10]
End Type
Local myGrid:TGrid = New TGrid
myGrid[0,1] = 2 'will use tile2.png

For Local X = 0 To 9
	For Local Y = 0 To 9
		DrawImage images[myGrid.coords[X,Y]], X*32, y*32
	Next
Next

Thanks Perturbatio, your help in this matter is greatly appreciated.
