Product Overview

The architecture of COBOL KeePIR consists of several key components. The COBOL parser analyzes the source code, identifying COBOL syntax and structures. The conversion engine transforms the COBOL code into AS/400 COBOL, handling language differences and syntax variations.

The data mapping module converts data formats, such as VSAM, DB2, and IMS, to DB2/400. The tool uses a command-line interface (CLI) for executing conversion tasks. Configuration files are used to define conversion rules and mappings.

For example, a configuration file might specify how to handle specific COBOL verbs or data types. The tool does not expose APIs. Communication between components is primarily internal.

The tool relies on the AS/400 environment for security, including user authentication and access control. Logging is provided for monitoring and auditing the conversion process. The tool's design focuses on automating the conversion process, reducing manual effort, and minimizing errors.

The CLI provides a flexible interface for batch processing and integration with other tools.

Frequently Asked Questions

What are the primary functions of COBOL KeePIR?

COBOL KeePIR automates the conversion of IBM mainframe COBOL to System i (AS/400) COBOL. It also converts CICS BMS Maps to AS/400 DDS, and various data formats like VSAM, DB2, and IMS to DB2/400. Additionally, it handles CICS/VSAM calls and JCL conversion.

How does COBOL KeePIR handle CICS BMS map conversion?

COBOL KeePIR supports the conversion of CICS BMS Maps to AS/400 DDS, facilitating the migration of screen definitions. This conversion ensures that the screen layouts and data fields are accurately translated for the AS/400 environment.

What data formats can COBOL KeePIR convert?

The tool converts various data formats including VSAM, DB2, CA Datacom/DB, CA ADS, CA IDMS, and IMS data to DB2/400. This conversion ensures data compatibility and allows for seamless integration with the AS/400 database environment.

How does COBOL KeePIR handle CICS/VSAM calls?

COBOL KeePIR converts CICS/VSAM calls to AS/400 COBOL file access commands, ensuring that file operations are correctly translated. This conversion maintains the functionality of file interactions within the migrated COBOL applications.

How does COBOL KeePIR convert JCL?

COBOL KeePIR converts z/OS and z/VSE JCL to System i CL, enabling the migration of batch job control. This conversion ensures that batch processes can be executed in the AS/400 environment.
