# 01 set b 57
# 02 set c b
# 03 jnz a 2         03-05
# 04 jnz 1 5         04-09
# 05 mul b 100
# 06 sub b -100000
# 07 set c b
# 08 sub c -17000
#   09 set f 1
#   10 set d 2
#     11 set e 2
#       12 set g d
#       13 mul g e
#       14 sub g b

#   27 set g b
#   28 sub g c             keep looping until b is as big as c
#   29 jnz g 2             29-31
#   30 jnz 1 3             30-EXIT
