But it can be used as often as necessary. This therefore takes up less memory space. Development becomes easier: By using procedures in a code, the modular programming can be properly implemented and thus every part of the code is written in a code. Now we can use these macros in the code segment. Some of these macros and procedures that I find most useful are: PRINT macro to print a string. Example usage: PRINT output. PUTC macro to print an ASCII character. Example usage: PUTC char. GET STRING procedure to get a zero-terminated string from a user until the Enter key. Each time a macro is called, the microprocessor's assembler places the macro's full set of instructions into the main program form where the call to the macro is made. Execution Time The procedures execute more slowly than the macros because every time a procedure is called, it must be integrated and linked to the. 4. Macros take up more memory only under certain circumstances: The macro is used more than once. The extended macro requires more memory than the code to call the procedure. Once the above is true, the large enough macrobody will be duplicated more than once, requiring more memory than the procedure, whose body is generated only once. Macros are expanded inline before the final compile step, while procedures are implemented in the final executable with call and ret operations. Basically, macros are syntactic sugars to make your source code prettier or make it faster for you to enter. To use the macro example from the link below, copied verbatim. Many book editors use macros to streamline the editing process, as I mentioned above, often as a kind of "house cleaning" before getting to the nitty-gritty of reading a project. Others use them at the end of a writing session to clean up any remaining errors. Writers can also use macros. They are not limited to editors. The execution time in a procedure is longer than that in a macro. a macro, the machine code is built several times. During a procedure, the machine code is only created once. The macro parameter is passed as part of an instruction that calls the macro. In a procedure, parameters are passed into registers or memory locations of the,
