* The input grid is currently stored in the tmp linked list.
*This routine shifts it to the dynamic grid list.

* Local definitions
	INTEGER next_used_grid,  next_free_grid 

* it is not necessary to do this in 2 stages, but it was simpler --
* just hacked from well-tested code

* take this grid from the "tmp" list and put it on the "free" list
* ... hook onto free list
	   next_used_grid   = grid_flink(grid)
	   grid_flink(grid) = grid_free_ptr  
	   grid_free_ptr    = grid
	   
* ... unhook from used list
	   grid_flink(grid_blink(grid)) = next_used_grid
	   grid_blink(next_used_grid)   = grid_blink(grid)

* take off the "free" list and put it at the start of the "used" list
* ... unhook from free list
	   next_free_grid  	= grid_flink(grid)
	   grid_free_ptr	= next_free_grid
* ... hook onto front of used list
	   grid_flink(grid)	 = grid_flink(max_grids)
