The date increment can be changed by changing the date interval in the
INTNX syntax.
%macro date_loop(start,end);
/*converts the dates to SAS dates*/
%let start=%sysfunc(inputn(&start,anydtdte9.));
%let end=%sysfunc(inputn(&end,anydtdte9.));
/*determines the number of months between the two dates*/
%let dif=%sysfunc(intck(month,&start,&end));
%do i=0 %to &dif;
/*advances the date i months from the start date and applys the DATE9. format*/
%let date=%sysfunc(putn(%sysfunc(intnx(month,&start,&i,b)),date9.));
%put &date;
%end;
%mend;
%date_loop(01jun2008,01sep2009)
