Hello, I am a SAS beginner and encounter a question as follows: I want to output two tables(parks, monuments) from one dataset, say, pg1.np_summary; While in output table parks I wanna keep variables Reg ParkName DayVisits; in output table monuments I wanna keep variables  Reg.  The following is my programming:    data parks monuments; set pg1.np_summary; where type in ('NM','NP');   if type='NP' then do; output parks; keep  Reg ParkName DayVisits; end; else do; output monuments; keep  Reg ; end; run;   However, I found the two output tables end up with having only one variable specified(Reg). May I know how to program that in order to have two output tables with different columns?  ... View more
