Multi-member files can get v. complex - especially in conjunction with
logical files (and multi-format logicals !).

You must remember that the member contains the data. A logical file
member can link to any member of a physical file - you must specify
at creation time how you want the links to work.

A logical member can point at from 1 to
32 members in a physical (or several physicals, in the case of multi-format
and
join logicals).  The DTAMBRS parameter defaults to *ALL, which means if you
create a logical file over a multi-member physical with the defaults, the
logical file will contain one member (as Mike noted above) which is scoped
over
all of the physical members, or over (I think it's the first) 32 if there
are
too many.  I've been burned by this one several times.
