Look at the documentation for top-level:*print-length*, which despite
the name controls the number of elements printed at the top level for
arrays and lists.  I would have to look, but I think you need to do
something special (setq-default??) to get this to work inside debugger
stack frames.  The Common Lisp variable *print-length* appears to only
control printing of lists, not arrays.

P.S. I assume you wanted to do something other then have a loop that
prints each element.
