What types of APIs does C/370 expose?

C/370 does not expose REST or SOAP APIs. It is a compiler and does not provide network-based APIs. Integration with other systems is typically achieved through compiled code that interacts with mainframe services and data.

How can I integrate C/370 with other systems?

C/370 supports integration through the use of native APIs and system calls. Developers can use C code to call mainframe services and access system resources. This involves using system-specific headers and libraries to interact with the operating system and other system components.

What protocols does C/370 use for communication?

The primary communication protocols used by applications compiled with C/370 depend on the specific application and its interactions with other systems. Common protocols include TCP/IP for network communication, and protocols specific to mainframe services, such as those used for database access or transaction processing.

How did C/370 contribute to application performance?

C/370 facilitated the development of high-performance applications on IBM mainframes. It provided features for optimization and efficient use of system resources. This enabled organizations to build and maintain critical business applications on the mainframe platform.

How did C/370 impact code portability?

By supporting the C programming language, C/370 allowed developers to write portable code. This facilitated the migration of applications between different mainframe environments and other platforms. It also enabled the reuse of code and reduced development costs.

What security features does C/370 offer?

C/370 does not have built-in security features like modern compilers. Security is managed at the operating system level. Access control relies on the mainframe's security mechanisms, such as RACF or similar security products. Authentication is handled through the operating system's user authentication processes.

What access control models are supported?

C/370 relies on the mainframe's security infrastructure for access control. This typically involves role-based access control (RBAC) or access control lists (ACLs) managed by security products like RACF. The compiler itself does not provide these features.

What encryption capabilities are available?

Encryption is not directly handled by C/370. Encryption of data and communication is managed by the operating system and other security products. The compiler does not provide encryption capabilities.

What audit and logging capabilities exist?

C/370 relies on the mainframe's auditing and logging capabilities. Security events and system activities are logged by the operating system and security products. The compiler itself does not provide its own audit logging.

What administrative interfaces are available?

Administrative interfaces are primarily provided through the mainframe operating system's tools. This includes the use of CLIs and system management consoles. C/370 itself does not have a dedicated administrative interface.

How is user management handled?

User management is handled through the mainframe operating system's user management tools. This typically involves using tools like RACF or similar security products to manage user accounts, permissions, and access rights. C/370 does not have its own user management system.

What are the main configuration parameters?

Configuration parameters are primarily set through compiler options and environment variables. These parameters control aspects such as include paths, library paths, and optimization levels. The specific parameters depend on the compiler version and the operating environment.

What monitoring and logging capabilities exist?

Monitoring and logging capabilities are provided by the mainframe operating system. System administrators can use system monitoring tools to track resource usage and performance. Logging is handled through system logs and security logs, which can be used to monitor the compiler's activities.

Product Overview

C/370's architecture comprised several key components. The compiler itself was the core, responsible for translating C source code into object code. The preprocessor handled directives like `#include` and `#define`.

The linker combined object files and libraries to create executable programs. The runtime libraries provided essential functions for C programs. Integration with the mainframe was achieved through system calls, allowing access to operating system services and hardware resources.

The compiler used system-specific headers to interface with the z/OS, z/VM, and zVSE/VSEn environments. The compilation process involved the following steps: preprocessing, compilation, assembly, and linking. The `CC` command initiated the compilation process.

The compiler did not have a dedicated database or storage mechanism; it relied on the mainframe's file systems and storage. Security was managed through the mainframe's security infrastructure, such as RACF, which provided authentication and access control. The compiler did not provide encryption capabilities.

The recommended migration path is to a supported C/C++ compiler for z/OS, such as OS/390 C/C++ or z/OS XL C/C++. The migration process involves recompiling the existing code with the new compiler and addressing any compatibility issues. The main differentiator was its mainframe compatibility.

Frequently Asked Questions

What is C/370?

C/370 is a compiler for the C programming language designed for IBM mainframe systems. It enables developers to write and compile C code for z/OS, z/VM, and zVSE/VSEn environments. It provides features for system programming, application development, and interfacing with existing mainframe applications.

How does C/370 compile C code?

C/370 supports the compilation of C source code into executable programs. It includes a preprocessor, compiler, and linker. The compiler translates C source code into object code, which is then linked with libraries to create an executable program. The compiler also provides options for optimization and debugging.

What are the common commands and syntax for C/370?

Common commands include `CC` for compilation, `LINK` for linking object files, and `EDIT` for source code editing. The syntax for compilation is `CC sourcefile.c -o outputfile`. Configuration often involves specifying include paths and library paths. These are typically set using environment variables or compiler options.

How does C/370 integrate with the mainframe environment?

C/370 integrates with the mainframe environment through system calls and interfaces. It allows developers to access mainframe resources and services. The compiler supports the use of system-specific headers and libraries, enabling interaction with the operating system and other system components.
