  2. IBM Basic assembly language and successors - Wikipedia

    en.wikipedia.org/wiki/IBM_Basic_assembly...

    Another reason to use assembler is that not all operating system functions can be accessed in high level languages. The application program interfaces of IBM's mainframe operating systems is defined as a set of assembly language "macro" instructions, that typically invoke Supervisor Call (SVC) [e.g., on z/OS] or Diagnose (DIAG) [on, e.g., z/VM ...

  3. Assembly language - Wikipedia

    en.wikipedia.org/wiki/Assembly_language

    Assembly language is typically used in a system's boot code, the low-level code that initializes and tests the system hardware prior to booting the operating system and is often stored in ROM. ( BIOS on IBM-compatible PC systems and CP/M is an example.)

  4. High Level Assembly - Wikipedia

    en.wikipedia.org/wiki/High_Level_Assembly

    Like the C standard library for the programming language C, the HLA Standard Library allows users to abstract away low-level operating system (OS) calls, so the same set of OS application programming interfaces (APIs) can serve for all operating systems that HLA supports. While an assembly language allows making any needed OS calls, where ...

    The SHARE Operating System (1959) for the IBM 709, IBM 7090, and IBM 7094 computers allowed for an loadable code format named SQUOZE. SQUOZE was a compressed binary form of assembly language code and included a symbol table. Modern IBM mainframe operating systems, such as z/OS, have available a symbol table named Associated data (ADATA).

  6. FASM - Wikipedia

    en.wikipedia.org/wiki/FASM

    It supports Intel-style assembly language on the IA-32 and x86-64 computer architectures. It claims high speed, size optimizations, operating system (OS) portability, and macro abilities. [2] [3] It is a low-level assembler [3] and intentionally uses very few command-line options. It is free and open-source software.

  8. Comparison of assemblers - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_assemblers

    Some assemblers are components of a compiler system for a high-level programming language and may have limited or no usable functionality outside of the compiler system. Some assemblers are hosted on the target processor and operating system, while other assemblers (cross-assemblers) may run under an unrelated operating system or processor.

  9. MMIX - Wikipedia

    en.wikipedia.org/wiki/MMIX

    MMIX is a computer intended to illustrate machine-level aspects of programming. In my books The Art of Computer Programming, it replaces MIX, the 1960s-style machine that formerly played such a role… I strove to design MMIX so that its machine language would be simple, elegant, and easy to learn.
