⟩ What do you understand by MACRO? Explain the various conditional constructs used while programming a macro?
- Macro can be considered to be a sequence of instructions to which a name is assigned.
- For short sequence of instructions which are of fixed nature Macros are used.
- They can execute faster as compared to subroutines.
- The MACRO directives are used to inform the assembler the starting of a macro.
- In order to enclose a macro the ENDM directive is used.
- The general format of the MACRO directive is :
Macro Name MACRO ARG1, ARG2 , …..,ARG N.
- To create macro sequences conditional assembly language statements are used. Theses statements control the flow of the program and are variations of the IF-THEN, IF-THEN-ELSE, DO-WHILE, and REPEAT-UNTIL constructs used in high-level language programming languages.
