Thank you
Maxim 2: Read the Log.
If it does not give you a clue right away, post it here, using the {i} button.
thank you
The output would look slightly different but you can use a CLASS statement instead of BY which will not generate the not sorted by BY variables error.
proc means strength=have mean std var; var s1 s2 s3 s4 s5 s6 s7; class program; run;
If you have large data with lots of values for the class variables there can be performance issues.
thank you
