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.
VAX MACRO is the computer assembly language implementing the VAX instruction set architecture for the OpenVMS operating system, originally released by Digital Equipment Corporation (DEC) in 1977. The syntax, directives, macro language, and lexical substitution operators of VAX MACRO formerly appeared in MACRO-11 , the assembler for the PDP-11 ...
The first of these, the Basic Assembly Language (BAL), is an extremely restricted assembly language, introduced in 1964 and used on 360 systems with only 8 KB of main memory, and only a card reader, a card punch, and a printer for input/output, as part of IBM Basic Programming Support (BPS/360).
The HLA v2.x language system is a command-line driven tool that consists of several components, including a shell program (e.g., hla.exe under Windows), the HLA language compiler (e.g., hlaparse.exe), a low-level translator (e.g., the HLABE, or HLA Back Engine), a linker (link.exe under Windows, ld under Linux), and other tools such as a ...
In computer programming, assembly language (alternatively assembler language [1] or symbolic machine code), [2] [3] [4] often referred to simply as assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions. [5]
The line-oriented debugger DEBUG.EXE is an external command in operating systems such as DOS, OS/2 and Windows (only in 16-bit/32-bit versions [1]).. DEBUG can act as an assembler, disassembler, or hex dump program allowing users to interactively examine memory contents (in assembly language, hexadecimal or ASCII), make changes, and selectively execute COM, EXE and other file types.

It is the successor to Program Assembler Loader , an earlier version of the PDP-11 assembly language without macro facilities. MACRO-11 was supported on all DEC PDP-11 operating systems. PDP-11 Unix systems also include an assembler (named as ), structurally similar to MACRO-11, but with different syntax and fewer features.
