SAS: Proc means output not as specified

Question

I want to output an extended Proc Means for my data. The standard is N, Min, Max, Std mean but I need also Median.

I have a lot of variables so I do not want to specify each individually after the output out= statement like median(var1)=var1_median etc.

The following does not work and just gives me the standard outputs:

proc means data=have n mean median std; 
output out= want_means (drop=_type_ _freq_);
run;

this one also doesnt work:

proc means data=have n mean median std; 
var volume price [xyz variables];
output out= want_means (drop=_type_ _freq_);
run;

Answer 1

I now use the following ,which works for me (note that I have to transpose it to have observations and not X variables...

proc means data=have; 
output out= want(drop=_type_ _freq_)
n= mean= median= std= /autoname ;
run;
proc transpose data=want
out=want; run;
