SAS users.
I have a dataset that contains sequentially named variables called telco_enq083, telco_enq084.
I am trying to write a macro that works out the horizontal sum of these variables for each observation.
Of course, test dataset is an extract of a much bigger dataset and I have more sequential variables(Full dataset has columns that look like -
telco_enq083, telco_enq084, telco_enq091, telco_enq092, telco_enq093, telco_enq094, telco_enq101... etc)
How would you modify the below macro to make it work? I have tried %SYSFUNC and it does not work and SAS says it cannot read the argument of the SUM function...
%LET a=telco_enq;
%MACRO Distribution(var);
DATA test2;
SET test;
%LET Total=SUM(of &var:);
RUN;
%MEND;
%Distribution(a);
I'm not sure why you would want to put this in a macro, or the result in a macro variable, but I think that the following does what you describe:
data test;
input telco_enq85-telco_enq90;
cards;
1 1 1 1 1 1
;
%global total;
%MACRO Distribution(var);
DATA test2;
SET test;
Total=SUM(of &var.:);
call symput('total',total);
RUN;
%MEND;
%Distribution(telco_enq)
%put &total.;
