What is a macro instruction explain?
A macro instruction is a request to the assembler program to process a predefined sequence of instructions called a macro definition. From this definition, the assembler generates machine and assembler instructions, which it then processes as if they were part of the original input in the source module.
What are macro instructions features?
Advanced Features of Macro Instructions
- The use of concatenation to generate type–specific instructions.
- Some standard system variable symbols.
- The use of one system variable symbol to solve the branch problem.
- Conditional assembly.
- The use of conditional assembly as a help in writing STKPOP.
What is macro explain with example in microprocessor?
Macro is a group of instructions. The Macros in Microprocessor assembler generates the code in the program each time where the macro is ‘called’. Macros can be defined by MACRO and ENDM assembler directives. Creating macro is very similar to creating a new opcode that can be used in the program.
What is macro in C++ with example?
A macro is a piece of code in a program that is replaced by the value of the macro. Macro is defined by #define directive. Whenever a macro name is encountered by the compiler, it replaces the name with the definition of the macro. Macro definitions need not be terminated by a semi-colon(;).
What is macro explain with example in system software?
A macro definition is a named sequence of statements you can call with a macro instruction. When it is called, the assembler processes and normally generates assembler language statements from the definition into the source module. The statements generated can be: Copied directly from the definition.

What is a macro instruction?
A macro instruction is a group of programming instructions that have been compressed into a simpler form and appear as a single instruction. When used, a macro expands from its compressed form into its actual instruction details. Both the name of the macro definition and other variable parameter attributes are included within the macro statement.
