data _null_;
set sashelp.class end = last;
call symput ('sname' || trim(left(_n_)) , name);
if last then call symput ('var_count' , _n_);
run;
%macro newvar;
data output;
set sashelp.class;
%do = 1 %to &var_count;
&&sname&i = (name = "&&sname&i");
%end;
%newvar;
%mend;
You can achieve something similar without macro coding:
data class;
set sashelp.class;
value = 1;
run;
proc transpose data=class out=want (drop=_name_);
by name age sex weight height;
var value;
id name;
run;
It is the same as
data have;
set sashelp.class;
dummy=1;
run;
proc logistic data=have outdesign=want(drop=intercept dummy) outdesignonly;
class name/param=glm;
model dummy=name;
run;
