Is there a way to subset data where you select variables to include that have a certain number of letters occurring in them in a particular order?
For instance, I want to select, out of a long list of variables the ones ending in 'RR'
First us the metadata in dictionary.columns to identify the variables of interest, and save them as a space-separated list in a macrovar named VARLIST:
proc sql noprint; select distinct name into :varlist separated by ' ' from dictionary.columns where libname='WORK'and memname='HAVE' and name like "_RR"; quit; %put &=varlist;
Then use that macrovar for your objective:
data want; set have (keep=&varlist); run;
