The major difference between Macro and Procedure is that the Macro is utilised for a small number of instructions, while on the other hand, the procedure is operated for a large number of instructions. Let’s find out more differences between macro and procedure.
What is Macro?
A macro in computer science is a set of rules or programmable patterns, which decrypts a specific sequence of input into a preset sequence of output. Macros are generally preferred for a small set of rules. Programmers can easily utilise macro anywhere in the program by employing its name.
What is Procedure?
Procedures are used for a large set of rules. They help make a large program more readable. It includes a set of instructions that executes a particular task.
Difference between Macro and Procedure
| S.No. | Macro | Procedure |
| 1 | A macro is a set of rules or programmable patterns, which decrypts a specific sequence of input into a preset sequence of output. | Procedures are used for a large set of rules that execute a specific task. |
| 2 | A macro is used for a small set of instructions. | A procedure is used for a large set of instructions. |
| 3 | We require more memory in the case of macro. | We require less memory in the case of the procedure. |
| 4 | In the case of macro, the CALL and RET instructions are not needed. | In the case of a procedure, CALL and RET instructions are needed. |
| 5 | In macro, the time of execution is lesser than the execution time needed in procedure. | In procedure, the time of execution is higher than the execution time needed in macro. |
| 6 | In the case of macro, the machine code is constructed several times. | In the case of a procedure, the machine code is created only once. |
| 7 | A macro parameter is passed as part of a statement that calls macro. | In a procedure, parameters are passed in registers and memory locations of the stack. |
