inline constant substitution

inline constant substitution

[Paul Rudin]

Suppose I have: 

#+CONSTANTS: foo=42

How can I make inline references to a constant on export in regular
text, rather than in a table?

I want to be able to write something like: 

  The value of foo is $foo 

in my org file, and then end up with:

  The value of foo is 42

when I export to LaTeX.

TIA.

Constants are for tables only. You can use a macro instead:

#+MACRO: foo 42

  The value of foo is {{{foo}}}.

Thanks. If I *also* want to use that value in a table is there a way to
do that? I experimented with:

#+TBLFM: @1$1={{{foo}}}

and 

#+TBLFM: @1$1="{{{foo}}}"

But neither of those work.

Should a noweb-ref be expanded as imagined inside of a table for this case?

Eg pseudo code:

,----
| #+NAME: foo
| #+begin_src emacs-lisp
| 42
| #+end_src
|
|
| #+NAME: ns
| |     n |
| |-------|
| |     1 |
| |     2 |
| | <<foo>> |
| |       |
`----

What about simply:

| {{{foo}}} |

i.e. put the macro reference directly in the table?

The value gets exported to LaTeX in the table, but that apparently
happens at export time. So if you have formulae in the table that refer
to that cell they don't compute using the value.
