The %macro statement does not run anything. It begins the definition of a macro. Later, you will see a matching %mend statement, ending the definition of the macro.
To actually run the macro, you then need to use:
%numest (dsin=some_value, dsout=some_value)
That's where you run the code and supply your data set names.
