Dear all,

Please remember that Keep and Drop statements are no functions.

They can't be called like one;


Those two example should produce the same result;
data Mydata;
 a=1;
 Todrop=2;
Run;
Data test1;
 set MyData;
 if 0=1 then do;
   Drop todrop;
 end;
Run;

Data test2;
 set MyData;
 Drop todrop;
Run;

Thanks,
Jacques Lanoue

Hi,

  do i=1 to 6651;
                if (snps[i] = "DD") then do;
                    call symput('keep',vname(snps[i])); /* Assign the
variable name which satisfies the condition to a MV /*
                    keep &keep;
                 end;
  end;

Thanks!
Akshaya
