What is a "null dataset"? Is this a data null step or a table with 0 rows?
sorry it means data _null_;
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;
