Create multiple IF statements for each argument in VaRList macro varaibble

Ronein — Mon, 13 Jan 2020 11:50:26 GMT

Hello

User define vector of dates.

For each of the argument I need to produce IF statement.


%let vector1='20NOV2019'd+'25NOV2019'd+'02DEC2019'd+'05DEC2019'd+'10DEC2019'd+'15DEC2019'd;
%let vector2=20NOV2019+25NOV2019+02DEC2019+05DEC2019+10DEC2019+15DEC2019;
%let n=6;
%put &vector1;
%put &vector2;
%put &n;


/*I need to produce following statements */
/*Then I will use it */
/*IF OFFER_DATE='20NOV2019'd then Accum_Loan=AccumTill_20NOV2019;*/
/*IF OFFER_DATE='25NOV2019'd then Accum_Loan=AccumTill_25NOV2019;*/
/*IF OFFER_DATE='02DEC2019'd then Accum_Loan=AccumTill_02DEC2019;*/
/*IF OFFER_DATE='05DEC2019'd then Accum_Loan=AccumTill_05DEC2019;*/
/*IF OFFER_DATE='10DEC2019'd then Accum_Loan=AccumTill_10DEC2019;*/
/*IF OFFER_DATE='15DEC2019'd then Accum_Loan=AccumTill_15DEC2019;*/


%macro mmacro; 
%do j=1 %to &n.;
%let date=%scan(&vector1.,&j.,+);
%let dateName=%scan(&vector2.,&j.,+);
IF OFFER_DATE=&date. then Accum_Loan=AccumTill_&date.;
%end;
%mend;
%put %mmacro;
/***I don't get the list of the statements as I want*/

Data b;
set a;
%mmacro;
Run;

Thanks for supplying code and what you expected.

It looks like you should have used dateName at the end of:

IF OFFER_DATE=&date. then Accum_Loan=AccumTill_&date.;

So that it becomes:

IF OFFER_DATE=&date. then Accum_Loan=AccumTill_&dateName.;

If this is not your issue then please show your log of the code being executed including any error messages.

Regards,

Amir.

See my answer to your previous question.

Dataset. Data Step. Call Execute.

@Ronein

Maybe you can try this, to avoid putting formatted dates into macro variables (this could play trick on you)

/* UNTESTED CODE */

data dates;
	input date:date9.;
	datalines;
20NOV2019
25NOV2019
02DEC2019
05DEC2019
10DEC2019
15DEC2019
;
run;

data _null_;
	set dates;
	call symputx("date"||left(_n_),date);
	call symputx("datef"||left(_n_),put(date,date9.));
	call symputx("nobs",_n_);
run;

data b;
	set a;
	do i=1 to &nobs;
		if OFFER_DATE=&&date&i then Accum_Loan=AccumTill_&&datef&i;
	end;
run;

Thank you very much.

Unfortunately the last step is not working and I get an error.

Please find the code that I run.

Kurt_Bremser — Tue, 14 Jan 2020 06:52:10 GMT

The ERRORs are caused by this:

%put %mmacro;

as you call the macro outside of a data step, and it creates data step code. Remove this unnecessary statement.

To get a macro to work, ALWAYS START WITH VALID, WORKING, NON-MACRO SAS CODE!!!

Create a data step that works for a few of your dates, THEN make it dynamic.

if offer_date = 21873 then accum_loan = accum_til_20NOV2019;

will only work if accum_til_20NOV2019 is already present in the dataset.

Is there a way to fix the code that way3 and way4 will work also?

You still have that wrong %put in there, causing the ERRORs in way 3.

Way 4 can't work, you can't mix data step and macro code like this; we've covered that a gazillion times by now.

THIS WORKS:

data a;
informat OFFER_DATE date9.;
format OFFER_DATE date9.;
input ID OFFER_DATE offer_Amount
AccumTill_20NOV2019  AccumTill_25NOV2019  AccumTill_02DEC2019
