Comments: To: sas-l@uga.edu

it seems as if a lot of SAS-Lers are heavily into embedding, but the variety
I see here is embedding SET or INFILE/INPUT statements within DO loops as in

data answer;
if _n_=1 then do until (lastobs);
   set monthsum end=lastobs;
   totalrev+revcargo;
end;
set monthsum;
pctrev=revcargo/totalrev;

OR

data quarter;
monthnum=month(today());
midmon=month(intnx('month',today(),-1));
lastmon=month(intnx('month',today(),-2));
do i = monthnum, midmon, lastmon;
     nextfile="c:\sasuser\month"!!compress(put(i,2.)!!".dat",' ');
     do until (lastobs);
        infile temp filevar=nextfile end=lastobs;
        input Flight $ Origin $ Dest $ Date : date9.
        output;
     end;
end;
stop;
