Difference between proc means and summary?

I have some knowledge on proc means and summary.

 

proc means : 1) The print option is set by default which displays output . 2) Omitting the var statement analyses all the numeric variable. Proc Summary : 1) No print option is set by default,which displays no output. 2) Omitting the variable statement produces a simple count of observation.

 

Can say me some more difference between two of the procedure other than two....

I think that's about it. Many years ago they did have slightly different functionality, but this converged with later versions of SAS, and I think it's just the default behaviour that is now different. Quite probably there is only one set of underlying code.

I believe Univariate, Summary and Means all use the same engine under the 'hood'. 

They have slight differences but the core functionality is the same.

When I started with SAS 5.1 Proc means only sent output to what is now the Listing destination. If you wanted similar output into a data set Proc Summary was required.

 

Default output datasets often have different structures for what appears to be identical code. Please see:

Proc means data=sashelp.class;
   class sex;
   output out=work.meansoutput ;
run;

Proc summary data=sashelp.class;
   class sex;
   output out=work.summaryoutput ;
run;

I actually continue to use Proc Means and Summary separately so when I look at my code I can quickly tell which was to create data sets and which was to display summaries.
