A compiler can thus make almost all the conversions from source code semantics to the machine level once and for all (i.e. until the program has to be changed) while an interpreter has to do some of this conversion work every time a statement or function is executed. However, in an efficient interpreter, much of the translation work (including ...
There are clear benefits when translating high-level code with an interpreter. Since object code is not created in the interpretation process, less memory is required for the code. [5] Interpreter languages do not create machine-specific code and can be executed on any type of machine. [7]
Machine code is generally different from bytecode (also known as p-code), which is either executed by an interpreter or itself compiled into machine code for faster (direct) execution. An exception is when a processor is designed to use a particular bytecode directly as its machine code, such as is the case with Java processors .
In computer programming, a programming language implementation is a system for executing computer programs. There are two general approaches to programming language implementation: [1] Interpretation: The program is read as input by an interpreter, which performs the actions written in the program. [2]
First implemented as a compile-and-go system rather than an interpreter, BASIC emerged as part of a wider movement towards time-sharing systems. General Electric, having worked on the Dartmouth Time-Sharing System and its associated Dartmouth BASIC, wrote their own underlying operating system and launched an online time-sharing system known as Mark I featuring a BASIC compiler (not an ...
An interpreter is computer software that transforms and then executes the indicated operations. [2]: p2 The translation process influences the design of computer languages, which leads to a preference of compilation or interpretation. In theory, a programming language can have both a compiler and an interpreter.
Computer-assisted translation is a broad and imprecise term covering a range of tools. These can include: Translation memory tools (TM tools), consisting of a database of text segments in a source language and their translations in one or more target languages.
The operating system preloads the interpreter for whatever language is required. These interpreters present different virtual machines for COBOL, Fortran, etc. Microdata produced computers in which the microcode is accessible to the user; this allows the creation of custom assembler level instructions.
