union
select var2 from dataset
union
select var3 from dataset;
quit;

Correct version (giving exactly the output you initially posted):
proc sql;
create table allvars as
select group, weight01 as weight from have
union all
select group, weight02 as weight from have
union all
select group, weight03 as weight from have;
quit;
Explicit method in a data step:
data want;
set have;
array weights {*} weight01-weight03;
do i = 1 to dim(weights);
weight = weights{i};
output;
end;
keep group weight;
run;
Or simply:
data want; set have (rename=(weight01=weight)) have (rename=(weight02=weight)) have (rename=(weight03=weight)); run;
