I want to achieve the same as:
data train_Sex(keep=Name Sex) train_Age(keep=Name Age) train_Height(keep=Name Height) train_Weight(keep=Name Height);
set sashelp.class;
run;
using a macro program with a list of variables. As far as I went:
* Build macro program;
%macro build_sets(var_list);
%let nwords = %sysfunc(countw(&var_list));
%do i=1 %to &nwords;
call symput("variable", %scan(&var_list, i));
data train_&variable(keep=Name &variable);
set sashelp.class;
run;
%end;
%mend;
* Run it;
%let var_list = Sex Age Height Weight;
%build_sets(&var_list);
But I am lacking the knowledge how can I dynamically change the "variable" var.
Thanks!
