Hi Everybody, Please help me to explain why in below the "%put &=u" is executed only once during the do-loop when i=5, while "put i=" is executed every iteration of the loop. The evidence is in the log below the code under line 76 and under line 79. Many thanks for the help. data loop;
do i=1 to 5;
call symput("u",put(i, 1.));
%put &=u;
put i=;
