%let var3=c;
%let var4=d;
%let var5=e;
%let x= &var1 %to &var5;
i need x=a,b,c,d,e
thank you
Hi,
If you really want to make use of "%to" for larger lists then you'll need to use it inside a macro definition, e.g.:
%let var1=a;
%let var2=b;
%let var3=c;
%let var4=d;
%let var5=e;
%macro makecsv(root,fromval,toval);
%let sep=;
%let makecsv=;
%do csvloop=&fromval %to &toval;
%let makecsv=&makecsv&sep&&&root&csvloop;
%let sep=%str(,);
%end;
&makecsv;
%mend makecsv;
%let x=%makecsv(var,1,5);
%put x=&x;

Amir.

So there could be many solutions, but do remember SAS Macro is nothing but a text string maneuver.
%let var1=a;
%let var2=b;
%let var3=c;
%let var4=d;
%let var5=e;
%macro cat;
%global x;
%let x=;
%do i=1 %to 5;
%if &i=1 %then %let x=&var1;
%else %let x=&x,&&var&i;
%end;
%mend;
%cat;
%put &x;
