contains:
An explanation of the ENFORM 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 statements, clauses, and
commands. The syntax of these language elements is described later in this
manual.
The syntax and functions of the ENFORM 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). 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 data base records, fields, and primary keys,
when including subscripts, and when naming using defined elements such as user
variables, user tables, user aggregates, or parameters.
