when we submit job or jobs ....jobs get different classes..
if job name is same output would be unpredictable coz MVS
can run any of the job..once job is executed MVS is not
going to execute another job with the same name.
so the jobs with the same name will be executed but output
will be unprectable.
1. There can be only 1 job in a jobcard.
2. There can be multiple jobs in the JCL(Job stream, I mean
the file-PS/PDS in which you have your jcl)
3. Say when you submit the JCL with 2 jobs, jobs will be
submitted, The job having class & priority as higher will
execute first. well let me give you an example.
