macro
adj 1: very large in scale or scope or capability
n 1: a single computer instruction that results in a series of
instructions in machine language [synonym: {macro}, {macro
instruction}]

macro \macro\ a.
very large in scale or scope or capability; as,
macroeconomics.
[WordNet 1.5]


Macro- \Mac"ro-\pref. [Gr. makro`s, adj.]
A combining form signifying long, large, great; as
macrodiagonal, macrospore, macromolecule, macrocosm.
[1913 Webster]


macro \macro\ n. [shortened form of macroinstruction]
1. a single computer instruction which symbolizes, and is
converted at the time of program execution or by a
compiler into, a series of instructions in the same
computer language.
[WordNet 1.5]

2. A keystroke (or combination of keystrokes) which
symbolizes and is replaced by a series of keystrokes; -- a
convenient feature of some advanced programs, such as word
processors or database programs, which allows a user to
rapidly execute any series of operations which may be
performed multiple times. Such macros may typically be
defined by the program user, without rewriting or
recompiling the program.
[PJC]

A name (possibly followed by a {formal argument} list) that is
equated to a text or symbolic expression to which it is to be
expanded (possibly with the substitution of {actual
arguments}) by a macro expander.

The term "macro" originated in early {assemblers}, which
encouraged the use of macros as a structuring and
information-hiding device. During the early 1970s, macro
assemblers became ubiquitous, and sometimes quite as powerful
and expensive as {HLLs}, only to fall from favour as improving
{compiler} technology marginalised {assembly language}
programming (see {languages of choice}). Nowadays the term is
most often used in connection with the {C preprocessor},
{Lisp}, or one of several special-purpose languages built
around a macro-expansion facility (such as {TeX} or {Unix}'s
{troff} suite).

Indeed, the meaning has drifted enough that the collective
"macros" is now sometimes used for code in any special-purpose
application control language (whether or not the language is
actually translated by text expansion), and for macro-like
entities such as the "keyboard macros" supported in some text
editors (and {PC} {TSRs} or {Macintosh} INIT/CDEV keyboard
enhancers).

macro: /mak´roh/, n. [techspeak] A name (possibly followed by a formal
arg list) that is equated to a text or symbolic
expression to which it is to be expanded (possibly with the substitution of
actual arguments) by a macro expander. This definition can be found in any
technical dictionary; what those won't tell you is how the hackish
connotations of the term have changed over time.The term macro originated in
