Hi!

I'm just trying to create a table of circle radii, areas and circumferences and has manually inputted the radii values as the variable 'Radius' but when I run the following code the output say "all data are missing because all levels of variable radius are missing." I'm not getting any errors in my log though. Thanks for any help!

DATA EC;
input Radius;
cards;
1 
3
5
7
9 
11 
13 
15 
17 
19 
21
;
run;
DATA EC;
pi=constant("pi");
circumference=2*pi*radius;
area=pi*(radius*radius);
run;
proc freq data=EC;
table radius*area*circumference;
run;

You are missing a SET Statement in your second data step

DATA EC;
   set EC;
   pi=constant("pi");
   circumference=2*pi*radius;
   area=pi*(radius*radius);
run;
