#
Now at 0
[-] (Clear N0)
>[<+>-]<
Layout now: N in 0
Place 'minus' in 1:
>+++++++++++++++++++++++++++++++++++++++++++++<
Place 'star' in 2:
>>++++++++++++++++++++++++++++++++++++++++++<<
Set line counter in 7:
>>>>>>>+<<<<<<<
Move N from 0 to 9 and 10:
[>>>>>>>>>+>+<<<<<<<<<<-]
Move N from 9 to 0 (leaving N in 10):
>>>>>>>>>[<<<<<<<<<+>>>>>>>>>-]<<<<<<<<<
Loop on (decreasing) N in 10:
>>>>>>>>>>[<<<<<<<<<<
Move decreasing N from 10 to 3 4 and 5:
>>>>>>>>>>[<<<<<+<+<+>>>>>>>-]<<<<<<<<<<
Move N from 5 to 10:
>>>>>[>>>>>+<<<<<-]<<<<<
Set 3 and 4 to decreasing N minus 1:
>>>->-<<<<
Print 'minus' (in 1) times in 3 (which is N minus 1) while zeroing 3:
>>>[<<.>>-]<<<
Move line counter from 7 to 8 and 9:
>>>>>>>[>+>+<<-]<<<<<<<
Add line counter from 9 onto 7 and 8:
>>>>>>>>>[<+<+>>-]<<<<<<<<<
Now 7 holds line counter and 8 holds 2*line counter
Subtract 1 from 8 to let it hold 2*line counter minus 1:
>>>>>>>>-<<<<<<<<
Print 'star' (in 2) times in 8 (which is 2*line counter minus 1) while zeroing 8:
>>>>>>>>[<<<<<<.>>>>>>-]<<<<<<<<
Print 'minus' (in 1) times in 4 (which is N minus 1) while zeroing 4:
>>>>[<<<.>>>-]<<<<
Add 1 to line counter (in 7):
>>>>>>>+<<<<<<<
Subtract 1 from decreasing N in 10:

Move N from 0 to 3 and 4:
[>>>+>+<<<<-]
Subtract 1 from 3 and 4 to let them contain N minus 1:
>>>->-<<<<
Print 'minus' (in 1) times in 3 (which is N minus 1) while zeroing 3:

Print 'star' (in 2) one time:
