Programming language implementation

An interpreted language is a programming language for which most of its implementations execute instructions directly, without previously compiling a program into machine-language instructions.

In computer science, lexical analysis is the process of converting a sequence of characters (such as in a computer program or web page) into a sequence of tokens (strings with an identified "meaning").

In computer programming, undefined behavior (UB) is the result of executing computer code that does not have a prescribed behavior by the language specification the code adheres to, for the current state of the program (e.g. memory).

In computer science, the term threaded code refers to a programming technique where the code has a form that essentially consists entirely of calls to subroutines.

An assembly (or assembler) language, often abbreviated asm, is a low-level programming language for a computer, or other programmable device, in which there is a very strong (generally one-to-one) correspondence between the language and the architecture's machine code instructions.

In computer science, an interpreter is a computer program that directly executes, i.

In computing, a linker or link editor is a computer program that takes one or more object files generated by a compiler and combines them into a single executable file, library file, or another object file.

Real mode, also called real address mode, is an operating mode of all x86-compatible CPUs.

In computing, a virtual machine (VM) is an emulation of a computer system.

A compiler is a computer program (or a set of programs) that transforms source code written in a programming language (the source language) into another computer language (the target language), with the latter often having a binary form known as object code.

Unspecified behavior is behavior that may vary on different implementations of a programming language.

The Micro programming language is a very basic programming language used in teaching computer science students principles of compiler construction.

Jasmin is a free open source assembler to create class files from human readable assembler-like syntax using the Java Virtual Machine instruction sets.

In the x86-64 computer architecture, long mode is the mode where a 64-bit operating system can access 64-bit instructions and registers.

A programming language implementation is a system for executing computer programs.

DIANA, the Descriptive Intermediate Attributed Notation for Ada, is an intermediate language used to represent the semantics of an Ada program.
