Product Overview

Barcode Print Facility is an API that provides barcode generation capabilities for mainframe applications. It supports languages such as COBOL, C/C++, Assembler, and PL/1, enabling developers to integrate barcode creation directly into their applications. The architecture typically involves the API residing within an LPAR on a mainframe, dependent on the z/OS or zVSE/VSEn operating system.

Applications call the API functions to generate barcode data, which is then sent to a printer. The main components include the API modules, configuration files, and printing subsystem interfaces. The API modules contain the functions for generating barcode data.

Configuration files define barcode types, printer settings, and other parameters. The printing subsystem interfaces handle the actual printing of the barcodes. Communication between components occurs through standard mainframe system calls.

The API modules are called from applications, and they in turn use system calls to access configuration files and the printing subsystem. Security is typically managed through the mainframe's security system (RACF, ACF2, Top Secret), which uses an access control list (ACL) model to control access to datasets and other resources. Monitoring involves tracking the printing subsystem to ensure barcodes are generated correctly and maintaining the configuration files.

Frequently Asked Questions

What does Barcode Print Facility do?

Barcode Print Facility is an API that enables mainframe applications to generate barcodes. It supports multiple programming languages, including COBOL, C/C++, Assembler, and PL/1, allowing developers to integrate barcode creation directly into their applications.

Is this a system, application, or tool?

Barcode Print Facility is a tool set that provides an API for barcode generation. It is not a complete system or application but rather a component that integrates into existing applications to add barcode printing capabilities.

What types of organizations use this?

Organizations that require barcode printing from mainframe applications, such as those in retail, logistics, or manufacturing, would benefit from this product. These organizations often need to generate barcodes for inventory management, shipping labels, or product identification.

When should we consider Barcode Print Facility?

A company should consider Barcode Print Facility when they need to integrate barcode generation into their mainframe applications. This is particularly useful when existing systems do not natively support barcode printing or when a standardized API is required across multiple applications.

What are the alternatives to Barcode Print Facility?

Alternatives include other barcode generation libraries or services, some of which might be platform-specific or require different integration methods. Examples include standalone barcode generator applications or cloud-based barcode APIs.
