9 definitions for macro From The Collaborative International Dictionary of English v.0.48 :
macro \macro\ a.
very large in scale or scope or capability; as,
macroeconomics.
[WordNet 1.5]
From The Collaborative International Dictionary of English v.0.48 :
Macro- \Mac"ro-\pref. [Gr. makro`s, adj.]
A combining form signifying long, large, great; as
macrodiagonal, macrospore, macromolecule, macrocosm.
[1913 Webster]
From The Collaborative International Dictionary of English v.0.48 :
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]
From WordNet (r) 2.0 :
macro
adj : very large in scale or scope or capability; "`macro' in the
word `macroscopic' is a combining form"
n : a single computer instruction that results in a series of
instructions in machine language [syn: macro instruction]
From Jargon File (4.3.1, 29 Jun 2001) :
macro- pref. Large. Opposite of micro-. In the mainstream and among other technical cultures (for example, medical people) this competes with the prefix mega-, but hackers tend to restrict the latter to quantification.From Jargon File (4.3.1, 29 Jun 2001) :
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 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 favor as improving
compiler technology marginalized assembler 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 [nt]roff
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 TSR or Macintosh INIT/CDEV
keyboard enhancers).
From The Free On-line Dictionary of Computing (27 SEP 03) :
MACRO
1. Assembly language for VAX/VMS.
2. PL/I-like language with extensions for string processing.
