Creating a column heading from a variable and text

chris_e — Mon, 05 Sep 2016 04:19:09 GMT

The following code checks whether an exposure value is less than 0 or . and if it is makes it 0. It then puts this into a new field called Raw_Agg_ and whatever the user puts in the variable cov, but I am unable to get SAS to create a new column header out of Raw_Agg_ and the macro variable cov

%macro expo_check(exposure_field, cov);
	
	if &exposure_field. < 0 or &exposure_field. = . then Raw_Agg_ || &cov. = 0;
		run;
%mend;

Any help would be greatly appreciated.

Thanks

You don't need the concatenation operator.

%macro expo_check(exposure_field, cov);
	
	if &exposure_field. < 0 or &exposure_field. = . then Raw_Agg_&cov. = 0;
		run;
%mend;

You probably don't need the run statement either. It should reside in the calling scope.

Thanks, that was easy I was trying all sorts of other complicated stuff.
