 Without the spaghetti code, and with comments to help code the logic of the V(R,C) array controlling the "walls" it makes sense and you can see how the later more confusing versions still do the same thing, just in a different set of GOTO to GOTO steps. Without the spaghetti code, and with comments to help code the logic of the V(R,C) array controlling the "walls" it makes sense and you can see how the later more confusing versions still do the same thing, just in a different set of GOTO to GOTO steps.
