INTRODUCTION TO ENABLE
How Does ENABLE Work?
• Used to maintain a small independent data base--Because a
standard ENABLE application typically does not maintain all
desired integrity constraints, you should modify the
application before you use it for a data base that requires
these constraints.
HOW DOES ENABLE WORK?
When you use ENABLE to generate an application, ENABLE performs
the following tasks:
1. Accepts specifications that describe your application
2. Opens a data dictionary and obtains a description of the
files to be accessed by your application
3. Stores information about the applications to be generated in
an internal table called the object table
4. Uses the information in the object table to:
--Transform a SCREEN COBOL skeleton file into SCREEN COBOL
source code
--Transform a PATHCOM skeleton file into a PATHCOM command
file
5. Calls the SCREEN COBOL compiler (SCOBOLX) to compile the
generated SCREEN COBOL source code
Figure 1-5 illustrates these tasks.
ENABLE supplies the SCREEN COBOL skeleton file and the PATHCOM
skeleton file. ENABLE allows you to modify these files before
you generate an application.
You must supply a data dictionary and specifications that
describe your application. Refer to Section 2 for information
about the tasks that you must perform to generate and execute an
application.
