You can build an IMAGE database in which only some of the datasets are
jumbo sets. You need to precede the set definition with the directive
$CONTROL JUMBO
to make it a jumbo set. You can turn the condition off with
$CONTROL NOJUMBO
In effect, all sets following this directive in the schema will be
non-jumbo sets.
 
By default, all sets are non-jumbo.
