SECTION 2

GENERATING AND EXECUTING AN APPLICATION--OVERVIEW

This section provides an overview of the tasks that you perform

to generate and execute an ENABLE application. These tasks are:

1. Providing a data dictionary that contains a description of

each file to be accessed by the application

2. Supplying specifications, in the form of ENABLE commands,

that describe the application

3. Creating the data base file (or files) to be accessed by the

application if the files do not already exist

4. Establishing a PATHWAY system to execute the application

PROVIDING A DATA DICTIONARY

A data dictionary is a set of files that document the structure

and organization of a data base. A data dictionary contains one

or more record descriptions; each record description provides a

format for the records stored in a data base file.

If a dictionary does not exist, you must create one before you

try to generate an application. Section 3 provides information

about creating a dictionary.
