Thanks to Nicolas too.

Do you mean like this:

\setkomavar{location}{\usekomavar{frombank}}

I don't understand why I would want to do that because I would have to
use a different LCO file depending on whether I was writing to my bank
or not.

Following on from my not understanding, any chance of an example of how
to do that showing what variable to set when writing to my bank, (to
cause the location variable to be populated with bank details)?

Err, yes it is?  And anyway, that data is in my LCO file, I don't want
to duplicate it.

Yes, that is what I have done (hmmm, I am beginning to sense a
fundamental misunderstanding here).  My bank account details are
permanent data and are in a LCO file.

The way you have edited my original email in your reply makes it
difficult to follow what is being discussed.  I would like to clarify
the main point by quoting from my original message:

#+BEGIN_QUOTE
...I would still prefer this way for the simple case of
inserting bank details:

______________________

** Change of address
:EXPORT_LOCATION: \usekomavar{frombank}

I have moved.
______________________

Where the frombank variable has been set in the LCO file:

\setkomavar{frombank}{\raggedright Acc.~No.:\,1234567890\\at Big
  Bank\\Sort Code: 11-22-33}

The bank details only appear in a letter when the property is set.
#+END_QUOTE

That property mentioned is the :EXPORT_LOCATION: property.  You can set
it to whatever you like, referencing something in your LCO file or
temporary data.
