[#for 0 10 1]

[# something...] <- put function here
  |
[#to_list]
  |
[list prepend 0]
  |
[s $0-myarrayname]

or

[#for 0 10 1]
  |
[#to_list]
  |
[list-map]x[something...] <- put function here
  |
[list prepend 0]
  |
[s $0-myarrayname]

and so on.

if you want random distributions, then those are defined in many more 
parameters than just an average value and an average deviation from that 
value. there are as many kinds of randomness as there are kinds of 
everything else. You can generate independent randomness (each sample is 
separate from each other) or you can make them related (random walks, 
markov chains, and more). First, you need to know what kind of effect 
you'd like to achieve or what you'd like to imitate, and after that, I can 
help you some more...

simple random walk in gridflow :

[#for 0 10 1]
  |
[# put 2]
  |
[# rand]
  |
[# * 2]
  |
[# - 1]
  |
[#scan +]
  |
[#to_list]
  |
...

first two boxes do the same as a «10 # 2» message in this case, because we 
just need to send the value «2» ten times to the randomizer, to flip a 
coin ten times...
