Hi all,
Splitting header arguments for source blocks into different lines works very
fine,
(and leads one to put more and more args in the header... )
Is there a chance or trick to do similarly when calling such src blocks?
Somehow like in shell scripts a backslash at the end of a line will signal
continuation?
(example see below)
Any suggestions or workarounds or best-practices to make the call lines
better readable and editable are welcome!
Kind regards,

Try using a custom babel language. Then using variable assignment from
babel block.
Here I define `fundamental' as a language, which means I can edit src
blocks like `lorem' in a src edit buffer in fundamental mode without
needing to do more than execute the `define-fundamental-as-babel' block or
put that defun in my .emacs. And when I execute the lorem block - as when
it is used in `:var txt=lorem()' - it returns the body as a string.
#+NAME: define-fundamental-as-babel
#+BEGIN_SRC emacs-lisp
(defun org-babel-execute:fundamental (body params)
(format "%s" body))
#+END_SRC
#+NAME: lorem
#+BEGIN_SRC fundamental
Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
#+END_SRC
#+NAME: abc
#+BEGIN_SRC emacs-lisp :results value :var txt="A B C"
(concat "txt-->" txt "<--txt")
#+END_SRC
#+CALL: abc( lorem() ) :results raw :wrap EXAMPLE
#+RESULTS:
#+BEGIN_EXAMPLE
txt-->Lorem ipsum dolor sit amet, consectetuer adipiscing elit.<--txt
#+END_EXAMPLE
BTW, there is already `org-babel-execute:latex', which is very handy for
editing LaTeX and then handing it to a src block for further processing.
HTH,
