   Yes, or if one were so inclined they could simply make four 
connecting lines using the Iline ROM_CALL. However, I never figured out 
how that ROM_CALL worked, so you might want to use Hline and Vline from 
Wak-A-Goomba source(but originally written by Andreas Ess). There also 
is a random number routine in Wakagoomba as well(in the main loop).
