Hello All,   I am trying to create a subgroup of varlist from the main %let statment outside the datastep, such that if I select the first one then %let will keep all the others except the selected. My initial throughts were to count all the variables through do loop and then count them agaim with another loop, and if first count (i) is not equal to the second count(j) then otherlist will contain all the rest of the vars. for example if %let varlist=a b c d e f g h; and when &next=a then &varlsit should be = b c d e f g h or if &next=b then &varlsit should be =a c d e f g h or if &next=c then &varlsit should be =a b d e f g h or if &next=d then &varlsit should be =a b c e f g h  and so on....     　 　 %let varlist=a b c d e f g h i j; %macro test(); %local i next ; %let i=1; %do i=1 %to %sysfunc(countw(&varlist)); %let next=%scan(&varlist,&i); %do j=1 %to %sysfunc(countw(&varlist)); %let otherlist=%scan(&varlist,&j); %end;   /*%let allvars = catx(" ", OF &other); */ %put &next &otherlist &allvars; %end; %end;   　 　 %mend;   %test();       My problem is that I'm not sure how to solve, or if this is even the right way to do it.  Please help me identify a solution! Please note, I have to do it outside the datastep.   Regards,       SAS 9.4 ... View more
