Question: The AS/400 uses single-level storage which, as I understand it,
decides where to put stuff.  Stuff is paged in and out off disk memory
regularly and often which is why an AS/400 can have so many devices attached
and still operate efficiently.  An array would be stored on disk too, just
like any other paging activity.

Why do you believe array processing to be less efficient than file
processing? I would think there would be more overhead associated with
using physical files since they consume disk space and maintain indexes.

IIRC, array processing is one of the most inefficient things that you can do
in an RPG program.
