Subject:      IN - Option

All,

Can someone please let me know , What exactly would be the use for using
IN option in data set

For e-g
data vacdata;
  length src $1.;
  set datasetA  (in=in1)
      datasetB  (in=in2);
  if in1 then src='1';  else src='2';
  format src $1.;
run;

I was trying to find the documentation , but somehow I am able to see only
for MERGE function, possible please send me the links with details If any
