I thought I understood "metaprogramming," i.e., creating generic code
blocks that can be called by any other code block regardless of programming
language -- but apparently I don't. I have this

 #+name: my-random-gen
#+header: :var n=0 :var lim=0
#+BEGIN_SRC emacs-lisp
(loop repeat n collect (random* lim))
#+END_SRC

and I have the variables initialized to zero. But now I don't know how to
call it with another code block. I've tried various versions of this

#+BEGIN_SRC emacs-lisp
my-random-gen(5 1.0)
#+END_SRC

and this various versions of this

#+BEGIN_SRC emacs-lisp :var results=my-random-gen() :var n=5 :var lim=1.0
results
#+END_SRC

to no avail. What am I missing? How can I actually use, call my-random-gen
in other code blocks?
