An Array of: arrays-of-arrays

If anyone could look through this example program and see what I want to do, that would be helpful. Each Area is a 2D-array of 2D-arrays. I want to put theses Areas into an array. That would mean an array of arrays of arrays. But blitz doesn't seem to allow this, and I don't know what to do. Graphics 800,600 Const amount=2'will change as I add a lot more. 'area works like areaID[width,height][,] Global Area0[,][,] Global Area1[,][,] 'it will soon get to like Area33[,][,] so I would like another array: 'like this Area[][,][,] 'Global Area[amount][,][,] 'this line does not compile! 'all areas[x,y] will point to one of these preexisting 3x3 arrays. Local dr2[,]=areaset(.. 0,0,0,.. 0,1,1,.. 0,1,1) Local row1[,]=areaset(.. 1,1,1,.. 0,0,0,.. 0,0,0) Local row2[,]=areaset(.. 0,0,0,.. 1,1,1,.. 0,0,0) 'etc. etc. there will be about 30 of theses 3x3 arrays 'the amount of area id's is constant but the width and height of each one differs. 'no maximum width or height. Global AreaWidth[amount] Global AreaHeight[amount] 'area with id=0 will be of size 2x2 areawidth[0]=2 areaheight[0]=2 area0=New Int[,][2,2] area0[0,0]=dr2 area0[1,0]=dr2 area0[0,1]=row1 area0[1,1]=row1 areawidth[1]=1 areaheight[1]=1 area1=New Int[,][1,1] area1[0,0]=row1 'draw each one Local areanow[,][,] 'pointer For id=0 To amount-1 'this IF shouldn't have to be here... If id=0 Then areanow=area0 ElseIf id=1 Then areanow=area1 'elseif id=... EndIf Cls DrawText "area "+id,500,0 For y=0 To areaheight[id]-1 For x=0 To areawidth[id]-1 drawx=x*35 drawy=y*35 SetColor 111,111,111 DrawRect drawx,drawy,30,30 SetColor 222,222,222 For y2=0 To 2 For x2=0 To 2 If areanow[x,y][x2,y2]=1 Then DrawRect drawx+x2*10,drawy+y2*10,9,9 EndIf Next Next Next Next Flip WaitKey Next 'Ititialize a 3x3 array Function AreaSet:Int[,](v00,v10,v20, v01,v11,v21, v02,v12,v22) Local a:Int[3,3] a[0,0]=v00 a[1,0]=v10 a[2,0]=v20 a[0,1]=v01 a[1,1]=v11 a[2,1]=v21 a[0,2]=v02 a[1,2]=v12 a[2,2]=v22 Return a EndFunction

OMG I just realized that this works: Global Area[,][,][amount] Allright, you just have to declare it backwards... but you access it like this: area[id][x,y]=some3x3array Is this backwards to anyone else?
