Dear Experts,
I am confused about how to use lob and call in org-babel. First I
define a simple function like square:
#+srcname: square(x)
#+begin_src python
return x*x
#+end_src
A line like
: #+lob: square(x=2)
does not seem to produce any result either in the buffer or on export:
#+lob: square(x=2)
The same seems to happen with call:
: #+call: square(x=2)
#+call: square(x=2)
Instead, to get things to work I need to do something like:
: | 4 |
: #+TBLFM: @1$1='(sbe "square" (x 2))
to get:
| 4 |
#+TBLFM: @1$1='(sbe "square" (x 2))
Thanks,
-I.S.

I'm not seeing this. The following works for me with C-c C-c on the
lob/call lines. However, note that the #+call line will *appear* not to
do anything as things stand, because it sees the existing results block
created by the #+lob call.
#+srcname: square(x)
#+begin_src python
return x*x
#+end_src
#+lob: square(x=2)
#+results: square(x=2)
: 4
#+call: square(x=2)
Is the above definitely not working for you? What version of org are you
using?

An equivalent example with slightly more visible output
--8<---------------cut here---------------start------------->8---
#+source: time
#+begin_src emacs-lisp
(current-time-string)
#+end_src
#+call: time()
#+results: time()
: Thu Aug 5 20:45:34 2010
--8<---------------cut here---------------end--------------->8---
Note, currently the parenthesis after "time" are required, which perhaps
shouldn't be the case -- Eric
