To start the demo program

Be sure the RDBMS data source is available and that all the non-Database Connectors™ environment variables required for your data source are set. To run the demo program, notify your COBOL development run time system that are interfacing to an RDBMS driver. You accomplish this by adding the following line to your ACUFH configuration file. (For information about the ACUFH configuration file, see the chapter Run-time Configuration.)

DEFAULT_HOST RDBMS_NAME

If you're running demo.cbl from the same directory in which you placed the XFD, you are ready to run. If the XFD (orderfile.xfd, created when you compiled the demo program) is in another directory, add the following line to the ACUFH configuration file:


XFD_PREFIX dir-containing-dictionary

Set any environment variables required for your specific RDBMS. For information on this, see the section Designating the Host Data Source or Designating the Host File System in the appendix specific to your particular RDBMS.

Run the demo program as usual.

The following screen appears:

Demo screen

The demo program lets you add, view, or change any of the rows (records) in the orders table. You can also view the source code for the demo program. When executed, the program creates an empty orderfile table in your target database. You may then add records to the newly created table.

The available menu options are:

First	View the first record in the file
Prev	View the previous record in the sequence
Next	View the next record in the sequence
Last	View the last record in the file
Delete	Remove the order that is being displayed from the database
Search	Enter the order number of the order to be viewed
Add	Resets the record to its initial state and increments the order number, putting you into edit mode with the new data
Edit	Allows you to add a record or modify the currently displayed record in the file
Help	Displays a short description of the demo program
Quit	Quit the demo program
