Did you run it? Also....you have some interesting variable names that make me not want to answer your question.

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;
