No. There are many, too many:

================================== 

to star :length
star.auxiliary random :length 
end

to star.auxiliary :random.number
repeat 36 [fd :random.length bk :random.length rt 10]
end

=================================
to star :length
make "random.length random :length 
repeat 36 [fd :random.length bk :random.length rt 10]
end

=================================
to star :length
let [random.length random :length] 
repeat 36 [fd :random.length bk :random.length rt 10]
end

=================================
create a slider called slider1

to star :length
setslider1 random :length
repeat 36 [fd slider1 bk slider1 rt 10]
end

=================================
instead of a slider use a textbox
