In the mid-1950s, when assembly language programming was the main way to program a computer, macro instruction features were developed to reduce source code (by generating multiple assembly statements from each macro instruction) and to enforce coding conventions (e.g. specifying input/output commands in standard ways). [31]
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.
The following description is taken from the original TTM reference manual [1] and the subsequent batch processing extension. [2]TTM is a recursive, interpretive language designed primarily for string manipulation, text editing, macro definition and expansion, and other applications generally classified as systems programming.
X macros are an idiomatic usage of programming language macros for generating list-like structures of data or code. They are most useful when at least some of the lists cannot be composed by indexing, such as compile time. They provide reliable maintenance of parallel lists whose corresponding items must be declared or executed in the same order.
The macro language can be used for functionalities as simple as symbolic substitution and as complex as dynamic programming. [8] SAS macro is considered to be a rich language, [22] although its overall syntax is very similar to that of base SAS. The names of macro variables in SAS are usually preceded by &, while macro program statements are ...
provides programming language capabilities; Unlike most earlier macro processors, m4 does not target any particular computer or human language; historically, however, its development originated for supporting the Ratfor dialect of Fortran. Unlike some other macro processors, m4 is Turing-complete as well as a practical programming language.
