Question 1

What was Whitesmiths C?

Accepted Answer

Whitesmiths C was a C compiler and runtime library designed for MVS and VM environments. It provided a foundational implementation of the C language, enabling developers to write system-level and application software. The compiler translated C source code into machine code for the System/370 architecture.

Question 2

What C language features did Whitesmiths C support?

Accepted Answer

Whitesmiths C supported the standard C language features, including data types, control structures, and functions. It also provided access to system-level functions and libraries specific to the MVS and VM operating systems. The compiler aimed to provide a high degree of compatibility with the C language standard.

Question 3

What were the primary use cases for Whitesmiths C?

Accepted Answer

The primary use case for Whitesmiths C was developing system software and applications on IBM mainframe systems running MVS and VM. It was used to create utilities, system extensions, and application programs that interacted directly with the operating system and hardware. The compiler was a tool for mainframe software development.

Question 4

How did Whitesmiths C relate to IBM C for System/370?

Accepted Answer

Whitesmiths C was a precursor to the IBM C for System/370 compiler. It provided the initial implementation and served as a basis for the later IBM product. The IBM C compiler offered enhanced features and support, building upon the foundation laid by Whitesmiths C.

Question 5

What were the common commands used in Whitesmiths C?

Accepted Answer

Common commands included `cc` for compilation, `ld` for linking, and `as` for assembly. The `cc` command would compile C source files into object files. The `ld` command would link object files and libraries to create an executable. The `as` command was used for assembling assembly language files.

Question 6

What was the syntax for basic operations like compiling and linking?

Accepted Answer

The basic syntax for compiling a C source file was `cc filename.c`. To link object files, the syntax was `ld object1.o object2.o -o executable`. Configuration files and interfaces were primarily handled through include files and system-specific libraries. These files provided declarations and definitions needed for compilation and linking.

Question 7

What types of APIs did Whitesmiths C expose, and how was integration achieved?

Accepted Answer

Whitesmiths C did not expose APIs in the modern sense (REST, SOAP). Instead, it provided a standard C library with functions for system calls and other operations. Integration was achieved by including header files and linking against the appropriate libraries during compilation. The primary communication method was through system calls.

Question 8

What were the main system components of Whitesmiths C, and how did they communicate?

Accepted Answer

The main system components included the compiler, linker, and runtime libraries. The compiler translated C source code into assembly code. The linker combined object files and libraries into an executable. The runtime libraries provided support functions for the compiled code. These components communicated through file I/O and system calls.

Question 9

What business value did Whitesmiths C provide?

Accepted Answer

Whitesmiths C enabled developers to create software for IBM mainframe systems. It provided a way to write system-level code and applications, contributing to the functionality and capabilities of the mainframe environment. It was a tool for building software on the System/370 architecture.

Question 10

How did Whitesmiths C contribute to the efficiency and performance of mainframe applications?

Accepted Answer

By using Whitesmiths C, developers could create efficient and optimized code for the mainframe. This led to better resource utilization and performance of applications. The compiler's ability to generate optimized machine code was crucial for maximizing the capabilities of the mainframe hardware.

Question 11

What role did Whitesmiths C play in the development of system software and utilities?

Accepted Answer

Whitesmiths C facilitated the development of critical system software and utilities. These tools were essential for managing and operating the mainframe systems. The compiler played a role in maintaining the stability and functionality of the mainframe environment.

Question 12

What security features did Whitesmiths C offer?

Accepted Answer

Whitesmiths C did not have built-in security features like modern compilers. Security was primarily addressed through the operating system's access controls and the security measures implemented in the applications developed using the compiler. The compiler itself did not provide authentication or encryption.

Question 13

How was user management and access control handled in Whitesmiths C?

Accepted Answer

User management was handled by the underlying MVS or VM operating system. The compiler did not have its own user management system. Access control was based on the operating system's security mechanisms, such as user IDs, passwords, and resource access permissions. The compiler relied on the OS for security.

Question 14

What audit and logging capabilities were available in Whitesmiths C?

Accepted Answer

Whitesmiths C did not include specific audit or logging capabilities. The operating system provided the primary means of auditing and logging system activities, including the execution of programs compiled with Whitesmiths C. Audit trails were managed by the OS.

Question 15

What administrative interfaces were available for Whitesmiths C?

Accepted Answer

Administrative interfaces were primarily command-line based, with commands executed through the MVS or VM operating system. There was no graphical user interface or web console. Configuration was managed through include files and system-specific settings.

Question 16

What were the main configuration parameters for Whitesmiths C?

Accepted Answer

The main configuration parameters were typically set through include files and system-specific settings. These settings controlled compiler behavior, library paths, and other aspects of the compilation process. The configuration was managed through text-based files.

Question 17

What monitoring and logging capabilities were available?

Accepted Answer

Monitoring and logging capabilities were provided by the MVS or VM operating system. The compiler itself did not have built-in monitoring or logging features. System administrators relied on the OS tools to monitor the execution of programs compiled with Whitesmiths C.
