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'

 

 

s1_dg_tif_FAD s1_dg_tif_NAD s1_dg_tif_RR

PROC Star

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;
--------------------------
The hash OUTPUT method will overwrite a SAS data set, but not append. That can be costly. Consider voting for Add a HASH object method which would append a hash object to an existing SAS data set

Would enabling PROC SORT to simultaneously output multiple datasets be useful? Then vote for
Allow PROC SORT to output multiple datasets

to match names ending in "_RR", use the condition

 

trim(name) like "%^_RR" escape "^"

 

or the condition

 

prxmatch("/_RR$/i", trim(name))
