Hi,
The documentation for #+call is rather confusing:
It is also possible to evaluate named code blocks from anywhere in
an Org-mode buffer or an Org-mode table. #+call (or synonymously
#+function or #+lob) lines can be used to remotely execute code
blocks...
Because aparently #+call only works on on a line by itself. Check the
following in ob-lob.el:
#+begin_src emacs-lisp
(defconst org-babel-lob-one-liner-regexp
(concat
"^\\([ \t]*\\)#\\+\\(?:"
(mapconcat #'regexp-quote org-babel-lob-call-aliases "\\|")
"\\):[ \t]+\\([^\(\)\n]+?\\)\\(\\[\\(.*\\)\\]\\|\\(\\)\\)"
"\(\\([^\n]*\\)\)\\(\\[.+\\]\\|\\)[ \t]*\\([^\n]*\\)")
"Regexp to match calls to predefined source block functions.")
#+end_src
This only matches whitespace at the beginning of line followed by
#+call (or lob or function), unlike the embedded calls of the form
src_<language>{body} which can be inlined.
Regards,
.j.
