"4,2,1,2,6"
# Ruby has no DO..WHILE construct. Need to write it as a WHILE
rnd = 0
while (rnd != 6)
rnd = rand(6)+1
print rnd
print "," if (rnd!=6)
end
rnd = 0
while (rnd != 6)
rnd = rand(6)+1

begin
rnd = rand(6)+1

# This uses Enumerators, ad it becomes almost functional style...

end
puts games.take_while {|roll| roll != 6}.join(",")
