Macro Do Loops does only one iteration

karthick_gopal — Tue, 07 Feb 2017 18:32:14 GMT

Hi,

I am running a simulation experiment in a loop. I have written a macro to run simulation for multiple times. The macro runs only once and produces no errors or warnings. I checked the syntax and also spent quite some time on debugging this. Everything seems fine.

Am i missing something?

Your macro has a %DO loop that uses the macro variable I.

One possiblity is that somewhere in some of the included program files you are setting the value of I to 3 or more so that the DO loop ends.

You might try something like

%put After datamanipulation.sas i=&i;

after each of the %include.

Or if you have any macros in any them ensure that all of their macro varaibles are explicitly set to Local.
