Looping a macro

[Demographer]

Hi,

I have a macro "microsim" with 2 parameters, which are a starting year and an ending year. I want to loop this macro by increasing the year by 5 from 2010 until 2060.

In other words, the loop should do:

%microsim(2010,2015);
%microsim(2015,2020);
%microsim(2020,2025);

...

%microsim(2055,2060);

I was thinking to do something like:

%macro loop(start,end);
   %local year;
   %do year = &start %to &end;
      %microsim (&start, %eval(&year+5))
   %end;

%mend loop;
%loop(2010, 2060);

But the do statement increases by 1 while I want by 5;

If you want an increment other than 1, use

%by
