Joep, the static DS only has one address no matter which invocation of
the procedure returns it.  That case might be a logic error, since the
contents of the DS would have record 2 and the application might expect
record 1, but the application would still have the ability and/or the
right to use the pointer.  In the other cases, *NEW etc, it would be
incorrect for the application to even use the pointer.
