Subqueries may be anywhere in an OPAL script¶
OPAL no longer requires subqueries to be at the beginning of an OPAL script. You may define them at any convenient location, as long as it is before the first use.

OPAL supports interval datasets, where each observation is associated with
an interval in time defined by a valid from and valid to time value. Use new
to create interval datasets from existing event datasets.
