Title:
  The aao record type could use a DOL input link

Status in EPICS Base:
  Triaged

Bug description:
  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.
