While I agree with the sentiment ... why would you want to ... it's not that lengthy.

 

data want;

set test;

recno = mod(_n_, 3);

if recno=0 then recno=3;

set test2 point=recno;

drop recno;

run;

What could possibly be the real business rule behind this operation?

Hi Astounding,

 

Thanks for providing us an excellent example of use of multiple set statments for combining datasets having many to many relationship. is there any alternative way? Just curious to know to increase the knowledge base.

Well, I suppose you could get the same observations, but in a different order, this way:

 

data want;

set test2;

do _i_=_n_ to _nobs_ by 3;

   if _i_ <= _nobs_ then do;

      set test point=_i_ nobs=_nobs_;

      output;

   end;

end;

run;

 

It's untested code, but looks like it should work.

Hi Astounding,

I was actually looking for an approaching other than using multiple sets statement.
