Rob, as Rod guessed, you can't count on ARY1, ARY2 and ARY3 being
contiguous.  To ensure they are contiguous, define an externally-described
data structure:

     d               e ds                  extname(ARRAYFILE)

Richard, you need a data structure for sure, whether or not you have
I specs or O specs.  (Either an externally-described DS, or a pgm-described
one that just lists the fields without the types.)

Just remember that I and O specs are really descriptions of move operations
between the I/O buffer and the fields.  They're also be used for
definitions,
if there isn't an explicit definition, but the definition isn't identical
to
the I spec.  For example, if you have a zoned (5,2) on an I spec, the
compiler
will define a packed (5,2) for you.
