What's the equivalent code using the new pointer syntax?

Local centre_ptr:Int Ptr

centre_ptr = centre_sqr                   ' pointer to centre square array

For Local square:Int = 1 To 64

  nearest_sqr = Var(centre_ptr)
  x = Var(centre_ptr+1) + board_x ; y = Var(centre_ptr+2) + board_y
                                                      
  ' etc

  centre_ptr :+ 3

This is I think

Local centre_ptr:Int Ptr

centre_ptr = centre_sqr                   ' pointer to centre square array

For Local square:Int = 1 To 64

  nearest_sqr = centre_ptr[0]
  x = centre_ptr[1] + board_x ; y = centre_ptr[2] + board_y
                                                      
  ' etc

  centre_ptr :+ 3

That doesn't seem to work Azathoth - but I use pointers throughout my program so it might be another routine that also needs to be modified.

Is 'Var(centre_ptr+1)' using an offset of 1 byte or 1 int (4 bytes)? If its 1 byte you might have to cast it to a byte pointer or use banks.

Int...

Local centre_ptr:Int Ptr
