Hi,

While using append procedure u may miss the variables that are not
present in the base dataset.

But while using 'set a b;'  stmt u can hold all the variables that are
present in both the datasets.

data a;
  s = 1;
  r = 2;
run;

data b;
 s= 3;
 t = 4;
run;

/********* Using Append Procedure************/
proc append base = a data = b force;
run;

proc print data = a;
run;

/*********** Using datastep ***********/
data a;
  set a b;
 run;

 proc print data = a;
 run;

Thanks,
Sasikumar,
Quartesian.
