Description:
This returns a reference to a data
object which has been stored in the database. The picture identifier signifies which picture to obtain
the reference from. If this identifier is negative then the current picture is used. If no reference object is
found for the given picture an error is returned. If the reference was created from an HDS locator then
an HDS locator is returned, and this should be annulled in the application using
REF_ANNUL to
ensure the file is properly closed.
