NewX  ( oldx dir -- newx )
  Advance the number in the direction as though it is a X coordinate. If
  the direction is north or south, leaves it alone, but if it is east or
  west then it is increased or decreased by one. The output is never less
  than zero nor exceeding the playfield width by more than one.

NewXY  ( oldx oldy dir -- newx newy )
  NewX and NewY together.

NewY  ( oldx dir -- newy )
NewY  ( oldy dir -- newy )
  Advance the number in the direction as though it is a Y coordinate.

nip  ( x y -- y )

o?  ( any -- bool )
  True if the value is an object (whether or not it has been garbage
  collected), or false for any other type. Error if it is a sound.

  specified object.

XYDir  ( dir -- newx newy )
  Finds the X and Y coordinates of the cell in the given direction.

YDir  ( dir -- newy )
  Finds the Y coordinate of the cell in the given direction.

,YDir  ( obj dir -- newy )
  Finds the Y coordinate of the cell in the specified direction of the
  specified object.
