What are the common commands and syntax used in VS COBOL II?

Common operations include compiling COBOL source code, linking object modules, and executing compiled programs. The syntax involves using JCL (Job Control Language) to invoke the compiler and runtime environments. Configuration relies on JCL parameters and system libraries.

What types of APIs and integration options are available?

VS COBOL II does not expose modern APIs like REST or SOAP. Integration primarily involves calling COBOL programs from other mainframe applications or using file-based interfaces. Communication protocols are based on mainframe networking, such as SNA.

What are the main architectural components of VS COBOL II?

Key components include the compiler, runtime library, and linkage editor. These components communicate through system calls and data exchange within the z/OS, z/VM, or z/VSE environments. Data storage relies on mainframe file systems and databases like VSAM.

How is VS COBOL II administered?

Administration is primarily performed through JCL and system utilities on the mainframe. User management is handled through the z/OS, z/VM, or z/VSE security systems. Configuration parameters are set via JCL and system initialization options. Monitoring and logging are managed through system logs and COBOL runtime diagnostics.

What business value did VS COBOL II provide?

VS COBOL II enabled organizations to maintain and evolve their COBOL applications on IBM mainframe systems. It provided a platform for business-critical applications, supporting data processing and transaction management.

How did VS COBOL II help with application modernization?

VS COBOL II facilitated the migration from OS/VS COBOL, allowing organizations to modernize their COBOL code and leverage new features and performance improvements. It supported the continued use of COBOL in enterprise environments.

What were the key benefits of using VS COBOL II?

VS COBOL II provided a stable environment for running COBOL applications, ensuring the continuity of business operations. It supported the processing of large volumes of data and complex business logic.

What authentication and access control methods are supported?

VS COBOL II relies on the security features of the underlying z/OS, z/VM, or z/VSE operating systems. It does not have its own built-in authentication methods. Access control is managed through the mainframe security systems, such as RACF or equivalent.

What encryption and audit capabilities are available?

Encryption is handled at the operating system and data storage levels. VS COBOL II itself does not provide encryption capabilities. Audit and logging are managed through the mainframe's system logging and security auditing features.

How are operations managed in VS COBOL II?

Operations are managed through JCL and system utilities on the mainframe. Monitoring is performed using system monitoring tools and COBOL runtime diagnostics. Troubleshooting involves analyzing system logs and COBOL error messages.

What are the key operational considerations for VS COBOL II?

Performance tuning involves optimizing COBOL code, JCL parameters, and system resource allocation. Capacity planning is based on the mainframe's resource utilization and application workload. Backup and recovery are managed through mainframe backup and recovery procedures.

Product Overview

The architecture of VS COBOL II comprised several key components: the compiler, runtime library, and linkage editor. The compiler translated COBOL source code into object modules. The runtime library provided the necessary support for executing compiled COBOL programs.

The linkage editor combined object modules and libraries to create executable programs. Communication between these components occurred through system calls and data exchange within the z/OS, z/VM, or z/VSE environments. Data storage relied on mainframe file systems and databases like VSAM.

VS COBOL II did not support modern API integration; instead, it relied on mainframe-specific methods. Security was managed through the underlying mainframe security systems, such as RACF, which provided authentication and access control. The product's architecture is now considered legacy, and migration to a supported COBOL compiler is essential for maintaining application functionality and security.

Frequently Asked Questions

What is VS COBOL II?

VS COBOL II is a COBOL compiler and runtime environment for IBM mainframe systems. It enables the development and execution of COBOL applications on z/OS, z/VM, and z/VSE platforms. It adheres to the ANSI COBOL 1985 standard.

How does VS COBOL II relate to OS/VS COBOL?

VS COBOL II was designed to replace OS/VS COBOL. While it requires recompilation and potential code adjustments, it offers enhancements and features not available in its predecessor. It was later replaced by COBOL for OS/390 and VM.

Which COBOL standards does VS COBOL II support?

VS COBOL II supports the ANSI COBOL 1985 standard. It does not support earlier COBOL standards. This compliance ensures a level of standardization in COBOL programming.

When was VS COBOL II first announced, and when did support end?

VS COBOL II was initially announced in 1988. Service and support for all platforms were discontinued by 2001.
