jEdit's macro editor. In computer programming, a macro (short for "macro instruction"; from Greek μακρο- 'long, large' [1]) is a rule or pattern that specifies how a certain input should be mapped to a replacement output. Applying a macro to an input is known as macro expansion.
In computer science, macroprogramming is a programming paradigm aimed at expressing the macroscopic, global behaviour of an entire system of agents or computing devices. [1] In macroprogramming, the local programs for the individual components of a distributed system are compiled or interpreted from a macro-program typically expressed by a ...
A general-purpose macro processor or general purpose preprocessor is a macro processor that is not tied to or integrated with a particular language or piece of software.. A macro processor is a program that copies a stream of text from one place to another, making a systematic set of replacements as it does so.
Macro (computer science), a set of instructions that is represented in an abbreviated format; Macro instruction, a statement, typically for an assembler, that invokes a macro definition to generate a sequence of instructions or other outputs; Macro key, a key found on some keyboards, particularly older keyboards.
If whitespace is present, the macro is interpreted as object-like with everything starting at the first parenthesis included in the replacement text. Expansion. The preprocessor replaces each token of the code that matches a macro token with the associated replacement text in what is known as macro expansion. Note that text of string literals ...
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.

A type of macro virus that cuts and pastes the text of a document in the macro. The macro could be invoked with the Auto-open macro so that the text would be re-created when the document (empty) is opened. The user will not notice that the document is empty. The macro could also convert only some parts of the text in order to be less noticeable.
This example aims to improve the readability of the X macro usage by: Prefix the name of the macro that defines the list with "FOR_". Pass name of the worker macro into the list macro. This both avoids defining an obscurely named macro (X), and alleviates the need to undefine it. Use the syntax for variadic macro arguments "..." in the worker ...
