In what language? In C, it was common for small utility services where people didn't want the overhead of a function. With the introduction of inline functions in C++, macros have been deprecated. They were often bad news anyway, because of side-effects.

Actually, when you say MACRO, this usually mean a set of commands...
When you make a function, you will define a step by step solution on what the function is intended to do...
The purpose of a macro is to automate common task in a single command or enabling a more powerful abstract.

Use macros for very short functions, i.e. one that would require simple selection or plain calculation. Use functions if the implementation would require blocks of code.

a macro generally generates inline code. There is no context switching, so it is faster than a function, particularly in inner loops.

Does the tool you are using have functions?
