@ -13211,14 +13211,8 @@ include anything in the Org mode file that takes a @code{#+NAME:},
@code{#+BEGIN_EXAMPLE} blocks, other code blocks, and the results of other
code blocks.
When a reference is made to another code block, the referenced block will be
evaluated whenever needed, in order to supply its value to the referencing
block. If the referenced block is cached (see @ref{cache}), its value will
be reused if possible, instead of being re-calculated. If the referring code
block is cached, its hash value will depend on the value of all the code
blocks it references. This system can thus be used to create a system of
as-needed re-evaluation among code blocks similar to that provided by
@uref{http://yihui.name/knitr/, knitr} or Sweave.
Note: When a reference is made to another code block, the referenced block
will be evaluated unless it has current cached results (see @ref{cache}).
Argument values can be indexed in a manner similar to arrays (see @ref{var,
Indexable variable values}).
