Dim and re-Dim of arrays

Part of some code that someone (oops can't remember who now :S) wrote for me on here was a vertex deformation thing. It involved storing the vertex coords in a little array matrix before manipulating them in turn.

However, I wanted to pull the deform code out into a separate function which means the Array is re-DIMmed in the function because its dimensions are dependant on the surface's number of verts I think.

I added a preliminary Dim statement in the main program, but either receive an "Expected )" error if I just try to add to the array in the function, or a "Duplicate Identifier" error if I re-Dim within the function.

Is it possible to re-Dim within a function?


Here's the relevant bits of the function code:

		Dim VertexMatrix#(CountVertices(CurrentSurface)-1,3)
  
		For CurrentVert=0 To CountVertices(CurrentSurface)-1

				Debug("DISTORT MESH","CHECKING COORDS FOR MESH: "+Mesh+" SURFACE: "+CurrentSurface+" VERTEX: "+CurrentVert)

			VertexMatrix#(CurrentVert,0)=VertexX(CurrentSurface,CurrentVert)
			VertexMatrix#(CurrentVert,1)=VertexY(CurrentSurface,CurrentVert)
			VertexMatrix#(CurrentVert,2)=VertexZ(CurrentSurface,CurrentVert)
			VertexMatrix#(CurrentVert,3)=0

Not to worry -

Solved it. I had included the VertexMatrix# handle as a parameter for the function. Blitz didn't liek that at all. All sorted now :)
