Public bug reported:

There is currently no way to copy numeric arrays between record fields
just using the core database record types. The only way I can think to
do it with any standard record type at all would be to use the aCalcout
from the synapps/calc module, but that is a rather heavy-weight
solution.

This functionality could most easily be provided by adding a DOL input
link (and a related OMSL field) to the aao record type. It should be
possible to do this in a backwards compatible way and not break existing
databases; I would want any solution offered to come with a unit test
program which demonstrates that not setting the DOL and OMSL fields
leaves the record's behavior exactly the same as it was. I suggest
writing the test before adding the new fields.
