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. The input and output may be a sequence of lexical tokens or characters, or a syntax tree.
In computer science, macroprogramming is a programming paradigm aimed at expressing the macroscopic, global behaviour of an entire system of agents or computing devices. 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 macro in computer science is a rule or pattern that specifies how a certain input sequence (often a sequence of characters) should be mapped to a replacement input sequence (also often a sequence of characters) according to a defined procedure. A macro is used to define variables or procedures, [1] to allow code reuse, or to design ...
Computing. 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. Media and entertainment.
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.
