[Akter]

I tried this below program its working in my SAS Base 9.4 version but not working in SAS Studio. Could you pls help me why is it, Is there anything i'm missing-

##############

%let N=120;
data CIop;
do i=117 to &N;

retain N x p L U alpha;
p=i/&N;
alpha=0.05;
if p=0 then L=0;
if p=1 then U=1;
if p ne 0 then L=(1-betainv(1-alpha/2, &N-i+1, i));
if p ne 1 then U=betainv (1-alpha/2, i+1, &N-i);
N=&N;
x=i;
**diff=L-U;
diff1=L-p;
diff2=round((U-L)/2*100, .01);
output;
end;
run;
proc print data=CIop;
var N x p L U diff2;
run;

Define "not working".  Show the SAS log and/or output.

Paste it as text into the window that pops up when you click on the Insert Code button on the forum editor.
