While I agree with Karma that the solution to this problem is to "
interleave" the two data sets using a set and by statement, his/her I don't
like the examples offered. Please take a look at the following code which
shows what to do if you already have three SAS data sets.
Data one;
input var;
cards;
123
456
Data two;
input var;
cards;
112233
445566
Data three;
input var;
cards;
111222333
444555666
run;
** add a line counter to each data set;
Data one;
set one;
line = _n_;
run;
Data two;
set two;
line = _n_;
run;
Data three ;
set three ;
line = _n_;
run;
* now interleave the three files using a set and by statement;
Data Final;
set one two three;
by line;
run;
Proc Print;
run;

You can use set and by statements to interleve the data.
