I kind of missed some of the posts for this, but if you really want them
to run one by one, you could give them their own job class and only
define one initiator for that class.

You're right that the user can certainly prevent the conflicts by making
sure his JCL always has a DISP=(OLD,DELETE).  However, since it does not
matter in an individual job, it's likely he has not done that or will
make a mistake at some time, causing unpredictable failures in the job
if you were to simply concatenate multiple jobs together..

And I think it would be difficult for the automated job submission tool
to find and correct this kind of error.
