It is possible in data step but give some example data sets. Instead I make a guess of what you want, you provide small example data sets and the output data set you desire.

data want;

     merge dataset_a dataset_b dataset_c;

     by idvar1 idvar2;

run;

But it depends on the type of join you want, left/right/inner/outer etc.  They all have differing requirements.
