You need to use dynamic allocation to allocate the datasets. Just
changing the dsn in the jfcb and using openj will only work if the
datasets are all on the same volume. Openj is trying to open the
additional datasets on the same volume as the _first_ dataset.

Another technique is to set the unlike conatenation bit in dcboflgs?
and have an open exit routine. The open exit routine will get called
at the start of each concatenated dataset after the first, so just
keep track of the open exit being called and correlate that to the
appropriate dataset. There used to be a section on this in one of the
data management guides.
