How is that different than Standard Deviation? Proc Means generates
that automatically.
*in output window;
proc means data=sashelp.class;
var age;
run;

*in a dataset;
proc means data=sashelp.class noprint;
var age;
output out=want (drop = _type_ _freq_) mean(age)=avg_age
std(age)=std_age;
run;

its not one of the standard statistics and is often calculated outside
but this should help.

The statistic you seek is called STDERR in SAS. It is computed by MEANS/SUMMARY and others. Did you even look at the documentation?
