Enform Plus Language Elements
An Enform Plus query is built with elements of the Enform Plus language. This section
contains the following:
•
An explanation of the Enform Plus language elements that are used throughout
query specifications. These elements are reserved words, special characters, and
comments.
•
A brief explanation of the functions of the Enform Plus statements, clauses, and
commands. The syntax of these language elements is described in Section 4,
Statements, Section 5, Clauses, and Section 6, Commands.
•
The syntax and functions of the Enform Plus language elements that can be used
either in a target-list or in request-qualification. (Both target-lists and request-
qualification are defined in Section 1, Introduction.) These language elements
include aggregates, literals, arithmetic expressions, logical expressions,
IF/THEN/ELSE expressions, parameters, user variables, and user tables.
•
The rules to be used when referencing database records, fields, and primary keys,
when including subscripts, and when naming user-defined elements such as user
variables, user tables, user aggregates, or parameters.
