What is a "null dataset"? Is this a data null step or a table with 0 rows?

Not perfect but may be all you need.

/* version 1 */

data _null_ ;
   if _n_ = 1 then
   do;
      file print;
      put 'All Vars';
      put _all_;
      file log;
      put 'All Vars';
      put _all_;
   end;

set sashelp.class;
/*... more statements ... */

run;

/* version 2 */
data _null_ varlist;
if 0 then output Varlist;

set sashelp.class;
/*... more statements ... */

run;

proc contents data=Varlist nodetails;
quit;
