large, or pertaining to an entire system; opposite of micro.

A prefix denoting a global perspective, one that views many small phenomena as aggregates (see aggregation ), e.g., macroeconomics, macrolinguistics, as opposed to the concern for the phenomena being aggregated thereby (see micro- ). (Krippendorff )

Monopoles, Astrophysics, and Cosmic Ray Observatory

n. A function of front end applications like The Wizard that allows a person to assign multiple commands to a single key, or keystroke combination. Relatively simple to create and very handy, macros are used by players who need to be able to quickly execute a command, or small set of commands. For example, a person could create a macro which would allow them to do a STANCE OFFENSIVE command, followed immediately by an ATTACK RAT command, which could be executed simply by pressing the F2 key, or Alt+R. Macros are simple and quick, but not as flexible as scripts.

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.

A macro is a series of commands carried out at the request of the user. For example if you repeatedly perform the same tasks every time you open a spreadsheet, you can record your keystrokes, save this as a macro. Next time you open the spreadsheet these keystrokes can be performed by simply running the macro

(1) A symbol, name, or key that represents a list of commands, actions, or keystrokes. Many programs allow you to create macros so that you can enter a single character or word to perform a whole series of actions. Suppose, for example, that you are editing a file and want to indent every third line five spaces. If your word processor supports macros, you can create one that consists of the following keystrokes:

Move Cursor to Beginning of Line

Move Cursor Down 1 Line

Move Cursor Down 1 Line

Move Cursor Down 1 Line

Insert 5 Spaces

Now you can enter the name of the macro, and the word processor will perform all these commands at once.

You can also use macros to enter words or phrases that you use frequently. For example, you could define a macro to contain all the keystrokes necessary to begin a letter -- your name, address, and a code that inserts the current date. Then, whenever you write a letter, you just press the macro key to include the letter header.
In a way, macros are like simple programs or batch files. Some applications support sophisticated macros that even allow you to use variables and flow control structures such as loops.

(2) In dBASE programs, a macro is a variable that points to another variable where the data is actually stored. In most other applications, this would be called a link.

A series of instructions which would normally be issued one at a time on the keyboard to control a program. A macro facility allows them to be stored and issued automatically by a single keystroke. Also called a script (e.g. in Pagemaker) or batch file (e.g. DOS).

The ability of a lens to focus very close (less than 8") for taking pictures of small objects at a 1:1 ratio.

A macro is a series of instructions defined so that a program, say Word, Excel, PowerPoint, or Access, carries out certain operations. As they are programs, they can be affected by viruses. Viruses that use macros to infect are known as macro viruses.
