Isn't that the problem? There is a default session for Caml code, so one does not need this argument. In my example, the function f is declared in one block and successfully used in the second. The function g is declared in a third (silent) block, and results in an error when we try to call it in the fourth and final block. Does this demonstrate the default session that Alan mentioned? G

I need to have some code in code blocks being run during export (as it's defining some functions for later questions), but I don't want anything to be displayed in the final document. At the moment I use the following options in the block: :results silent :exports results Is it the correct way to do it? Thanks, Alan Yes, this is the correct combination of header arguments for this use case. Cheers, -- Eric Schulte http://cs.unm.edu/~eschulte

If you replace `none' by `results' for the `:exports' of the first block, then everything works fine. I don't think this is specific to ocaml, I guess it may happen with every session-based evaluation. Alan
