What are you calling "job ID"? This could be the JES number of the job, which is unique, or it could be the job name, which may not be unique. Furthermore, how are you planning on doing the file naming in the subsequent step? Since the job JCL is fixed when JES runs the converter / interpreter (at the time the job is submitted), you CANNOT change the data set name in the JCL.
Job name and JES number are not that hard to retrieve, but I am not aware of any simple way to retrieve step completion codes while the job is running; check with the job scheduler in use at your site -- I know CA-7 allows testing of step completion codes in JCL.
