PROC REPORT within DATA in SAS - sas

Question

I am trying to do a simple thing - write a PROC REPORT procedure within a DATA sentence. My main idea is - if the condition in data step is true - lets execute PROC REPORT, if it is false - do not execute PROC REPORT. Any ideas? Code runs without errors for now, but I see that condition in IF statement is not applied and PROC REPORT is ececute despite the fact that condition is not fulfilled.
Thank you in Advance.

Answer 1

To conditionally execute code you need to use a macro so that you can use macro logic like %IF to conditionally generate the code.
But for your simple problem you can use a macro variable to modify the RUN; statement on your PROC REPORT step. Create a macro variable and set it to the value CANCEL when you don't want the step to run.
%let cancel=CANCEL;
...
if abs(difference) > 10 and abs (difference1) > 107 then call symputx('cancel','');
...
proc report ... ;
...
run &cancel ;
Simple example. Produce report if anyone is aged 13.
%let cancel=CANCEL;
data _null_;
set sashelp.class ;
if age=13 then call symputx('cancel',' ');
run;
proc report data=sashelp.class ;
run &cancel;

Tom's answer is a good one, and probably what I'd do. But, an alternative that is more exactly what you suggested in the question seems also appropriate.
The way you execute a PROC REPORT in a data step (or execute any non-data-step code in a data step) is with call execute. You can use call execute to execute a macro, or just a string of code; up to you how you want to handle it. I would make it a macro, because that makes development much easier (you can write the macro just like regular code, and you can test it independently).
Here's a simple example that is analogous to what Tom put in his answer.
%macro print_report(data=);
proc report data=&data.;
run;
%mend print_report;
data _null_;
set sashelp.class ;
if age=13 then do;
call execute('%print_report(data=sashelp.class)');
stop; *prevent it from donig this more than once;
end;
run;
