What is the difference between macro and subroutine?

Answer Posted / digant mehta

Subroutine: When a task is to be done repeatedly then it is written as subroutine and this subroutine will be called each time to perform that task.Subroutine program will be stored in some memory location and program control will be transfered to that location each time.where as in macro the number of instructions will be less than subroutine.Here each time u call a macro that set of instructions will be inserted in that location.It is faster than subroutine.But memory requirement is more than subroutine.
