Hi all,
I have a problem with implementing a DO loop using date variables as by-variable.
I have searched this community and found a way. But there comes an error when I tweak a little.
See the code first. This one works fine.
options symbolgen;
%macro daily00(X) /des = "Sample Macro";
%do i=1 %to 3;
%put &X._&i;
%end;
%mend daily00;
%macro iteration00(BeginDate, EndDate) /des = "Sample Macro";
%do j=%sysfunc(inputn(&begindate,date9.)) %to %sysfunc(inputn(&enddate,date9.));
%daily00(X=&j);
%end;
%mend iteration00;
%iteration00(BeginDate=23Dec2014, EndDate=24Dec2014);
Now I want to change the BeginDate and EndDate to YYYYMMDD, so in this case it would be 20141223 and 20141224, respectively.
I tried the below but something's wrong. I think I am confused with INPUT or INFORMAT syntax, but I am lost.
options symbolgen;
%macro daily00(X) /des = "Sample Macro";
%do i=1 %to 3;
%put &X._&i;
%end;
%mend daily00;
%macro iteration00(BeginDate, EndDate) /des = "Sample Macro";
%do j=%sysfunc(inputn(&begindate,8.)) %to %sysfunc(inputn(&enddate,8.));
%daily00(X=&j);
%end;
%mend iteration00;
%iteration00(BeginDate=20141223, EndDate=20141224);
The reason I am trying to use date format in this DO loop is because, I want to avoid numeric values such as 20141240 when calling datasets in the DAILY00 macro.
I am using SAS 9.4.
Any help is appreciated.
Yes, the informat is incorrect. You are using:
8.
But should be using:
yymmdd8.
Also note, you define %daily00 using X as a positional parameter. But your macro call uses it as a keyword parameter. Presumably that's just a typo.

Thanks you. It works!
I was keep trying
yymmddn8.
since the numbers didn't have any usual delimiters such as / or -.
Anyway, thank you so much!
