Hello,

I have a SAS progam like this format. I wonder how does it executes? Thanks !

%macro a (par1 = );
    .........
	.........

	%macro b (par2 =);
	  ........
	  ........
	%mend b;

	%b;
       .........
       .........
%mend a;
   
%a;

Basically, the code does the following

1. Declares an inner macro (b) and executes it as part of the of the outer macro (a) declaration

2. Executes the newly declared macro (a)

FYI - this is not a good way to write code, nesting macro definitions is inefficient for starters.
