Barr/RJE

The architecture of Barr/RJE consists of several key components designed to facilitate file transfer and remote job entry between DOS/Windows and mainframe systems. The communication module handles TCP/IP connections, managing the network interface and data transmission. The data conversion module translates data formats between the DOS/Windows environment and the mainframe's EBCDIC format, ensuring data integrity during transfer.

The job management module is responsible for submitting jobs, retrieving output, and monitoring job status. Configuration is primarily managed through configuration files, which define mainframe connection details (IP address, port), job parameters (job name, class), and file transfer settings. The software does not expose any specific APIs.

The product uses a command-line interface for operations, with commands such as `SUBMIT ` to submit files, `RETRIEVE ` to retrieve output, and `STATUS ` to monitor job status. Authentication is based on user IDs and passwords. Logging is implemented to track file transfer activities and system events, providing an audit trail.

Compared to competitors, Barr/RJE offers a streamlined approach to RJE, focusing on ease of use and integration with Windows environments.
