Thanks very much for your reply Eric.
So the ":results org" feature was there all along.
Searching for "raw" in "org-babel.el" shows it's nicely
explained in the doc-string for "org-babel-insert-result".
(maybe I should have done that sooner)
I also noticed the ":results html" and ":results latex"
options which look very useful.
The latex option encloses the output in a
#+BEGIN_LaTeX ... #+END_LaTeX block, which is nice because
when the source block is re-executed, the new results
replace the old results.
-- Would it be possible to have something like that for "raw"
or "org" mode?
(Maybe that would need a #+BEGIN_org ... #+END_org kind
of construct.)
Also, I've been looking at #+lob: which looks like another
really useful idea, and there are two things I am wondering
about.
-- Is it possible to use #+lob: with ":results output org" ?
-- Is it possible for #+lob: to take a string argument ?
The 4 examples below show things I have tried.
1. and 2. work fine.
3. and 4. are what I can't work out.
Thanks for any ideas you have about these things.

--------------------------------------------------
1. :results output org -> works
--------------------------------------------------
#+srcname: randone
#+begin_src ruby :results output org
description = "lucky"
number = 3
maximum = 100
puts "* Random numbers\n" +
"Here are some #{description} numbers: " +
(1..number).collect {|x| (rand * maximum).ceil }.join(", ") +
"."
#+end_src
#+resname: randone
* Random numbers
Here are some lucky numbers: 48, 69, 6.
--------------------------------------------------
2. :results value -> works with #+lob:
--------------------------------------------------
#+srcname: randtwo(n,max)
#+begin_src ruby :results value
number = n
maximum = max
"* Random numbers\n" +
"Here are some random numbers: " +
(1..number).collect {|x| (rand * maximum).ceil }.join(", ") +
"."
#+end_src
#+lob: randtwo(n=3,max=100)
#+resname: randtwo(n=3,max=100)
: * Random numbers
: Here are some random numbers: 14, 77, 75.
--------------------------------------------------
3. :results output org -> doesn't work with #+lob:
--------------------------------------------------
#+srcname: randthree(n,max)
#+begin_src ruby :results output org
number = n
maximum = max
puts "* Random numbers\n" +
"Here are some random numbers: " +
(1..number).collect {|x| (rand * maximum).ceil }.join(", ") +
"."
#+end_src
#+lob: randthree(n=3,max=10)
#+resname: randthree(n=3,max=10)
: nil
--------------------------------------------------
4. Not sure how to use string argument with #+lob:
--------------------------------------------------
#+srcname: randfour(n,max,desc)
#+begin_src ruby :results value
description = desc
number = n
maximum = max
"* Random numbers\n" +
"Here are some #{description} numbers: " +
(1..number).collect {|x| (rand * maximum).ceil }.join(", ") +
"."
#+end_src
#+lob: randfour(n=3,max=100,desc="lucky")
#+resname: randfour(n=3,max=100,desc="lucky")
: randfour
