Macro (short for “macro help”) requests an assembler program to handle a predefined sequence of instructions called a macro definition. It is a programmable pattern that converts a set of input values into output values. By representing a complex series of keystrokes, mouse gestures, instructions, or other forms of notes, macros can make tasks less stressful. Macro definitions for I / O operations, data management, and admin operations that you can contact for processing by coding required macro instructions. Macros is a technique in computer programming that helps a developer to reuse code.
You can also set up your macro definitions and call them by coding the corresponding macro instructions. Instead of encoding all of that sequence every time you need it, you can create a macro instruction to represent the sequence and then, every time the sequence is required, encode the macro instruction statement. During assembly, the instruction sequence represented by the macro instructions is entered into the source program. The compiler creates machine and compiler instructions, which it then processes as if they were part of the original entry in the source module.
Macros are used in Microsoft Office applications such as PowerPoint, Word and Excel to automate various functions to make it easier for end-users to perform specific tasks or display different content types. Macros for Office applications are written using a programming language called Visual Basic for Applications (VBA). Macros must be recorded primarily to repeat commands. Most Excel users manage their tasks through a series of icons assigned to them. If you finish using one worksheet and no longer want to use the same commands on other spreadsheets, you can always customize the previous macros or delete them entirely on your computer.
