UO.DropC
From OpenEUO
UO.DropC(contid[,nx,ny])
The UO.DropC command drops obects you drag using the UO.Drag command to any container you want.
If you specify nx/ny then the item will be dropped in the container at the coordinates relative to the container's location, otherwise it will be dropped on the container.
If you want to combine the stack being dragged with another stack of the same item type, just pass the ID of the destination stack as contid.
Do not use this command to terminate a drag initiated by the UO.CliDrag function
