Use the configuration variable DEFAULT-HOST to establish Informix as your file system:
DEFAULT-HOST informix
Next, select the particular Informix database to be accessed by your COBOL application. Identify this database to the runtime system via the configuration variable DATABASE:
DATABASE database-name
The database you choose might be one that has been in use at the site for some time, and already contains data, or it might be a new, blank database that has just been created and named.
NOTE
The Acu4GL interface to Informix allows you to create a file with an OPEN OUTPUT statement, just as you can create Vision indexed files. The Informix equivalent of a Vision file is a table, not a database. You need to have a pre-existing database for your Informix tables, just as you need to have a pre-existing directory for Vision files.
To create a new, blank database, use Interactive SQL (ISQL) or dbaccess from Informix. If neither dbaccess nor ISQL is available at your site, use the utility program sql.acu provided on your Acucorp medium, as noted immediately below.
IMPORTANT
You are now ready to use the sql.acu program.
After you learn about and use this utility, you will next find out about preparing and compiling your COBOL program , followed by learning to use the demonstration program.
