Multi dimensional arrays

Hi people. I need to know how to define an array within a type, using a function (within the type) which takes the arrays dimensions which are passed to it.

Type gameBoard

	Global x,y,z,width,height,trans;
	Global layer;
	Global data[1,1];  <-----THIS IS THE ARRAY I WOULD LIKE TO SPECIFY THE SIZE OF FROM CALLING A FUNCTION

	Global cellWidth = 10;
	Global cellHeight = 10;
	
		
	Function createBoard:gameBoard(getWidth,getHeight)
		layer:+1;
		width = getWidth;
		height = getHeight;
		data=data[getWidth,getHeight]	
		'use slice to resize array
		Return New gameBoard;
	End Function
	
	Method drawBoard()
		'For Local repx=EachIn data
		For repx = 0 To (width-1)
			For repy = 0 To (height-1)
				xpixel = repx*cellWidth;
				ypixel = repy*cellHeight;
				data[repx,repy] = 1;
				If data[repx,repy] = 1 Then DrawOval(x+xpixel, y+ypixel, cellWidth, cellHeight);
			Next
		Next
	End Method
	
End Type

I would like to know how to accomplish this without using lists :)

Thankyou for any help
