Enform Plus Terminology
The important terms are:
Query specifications. The language elements (statements, clauses, commands, and so
on) that you specify to provide Enform Plus with the information it needs to retrieve
data and to establish the query environment.
Query. One complete LIST or FIND statement. Both statements specify the
information to be retrieved.
Target-list. A part of the query; a target-list consists of target-items and a special type of
target-item called a by-item.
Target-items. Any record names, field names, variable names, aggregate names, literals,
or expressions, excluding by-items, whose values you want to appear as output from
your query.
By-items. Field names modified by the BY or BY DESC clauses described in Section 5,
Clauses. The values of the fields are used to sort and group the query output.
