shell script to find zero byte files

In which i have several directories 1,2,3,4....
Now, In each of these directories i have several files a.dat, b.dat, c.dat, d.dat.....

MYDIR

---------a.dat
---------b.dat
---------c.dat
---------d.dat
----2
---------a.dat
---------b.dat
---------c.dat
---------d.dat
----3

DESCRIPTION

       sdpa  - "SDPA (SemiDefinite Programming Algorithm)" is one of the most efficient and stable software packages for solving SDPs based on the
       primal-dual interior-point method.

       SDP (SemiDefinite Program) is used for financial engineering, machine learning, control theory, sensor network problem, quantum	chemistry,
       quantum information, combinatorial optimizaiton, polynomial optimization, and so on.

       Futher information on SDP and SDPA can be found at
       http://sdpa.sourceforge.net/
