  I've been using embedded calc for some time now and have been looking for an
answer to the following:

Is it possible, from "calc" to read embedded calc variables?

Suppose I have the following in a file:

myVariable := 1.5 + 13 => 14.5

Hitting C-x * u will refresh "14.5" and now embedded calc knowns about 

If I switch to "calc mode" (C-x * c), how can I get access to "myVariable"?

>From the embedded calc manual:

"The assignment operator `a := 17' does not actually do anything by itself. But
Embedded Mode recognizes it and marks it as a sort of file-local definition of
the variable."

How can I access these "file-local definitions"?  Also, is it possible to set
"embedded" calc variables from calc?
