Submit job in CL

["Malini Rao" <malini2005@xxxxxxxxxxxxxx>]

Dear members, 

I have a CL program program that submits 3 jobs - Job A , Job B, Job C.

The CL program needs to submit a 4th job too - Job D - BUT only on completion 
of the previous three jobs.

How will the logic to submit the 4th job on completion of the first 3 be 
incorporated in the CL program ? - Also we don't have the full qualified name 
of any of the jobs

Thanks in advance,
Malini
