Ouch.... that is a hard ugly one.
Split up your jobs in separate jobs or try dynamic, but conditional allocations?
Or insert steps to check for dsn, like this Clist example in a IKJEFT step:
PROC 0
IF &SYSDSN('???.JCL') = OK THEN +
DO
WRITE DATASET FOUND
SET &RC = 0
END
ELSE +
DO
WRITE DATA SET NOT FOUND
SET &RC = 4
END
Use that RC to do your IF checking...

Perhaps if there is a way to check the status of a VOLSER in a batch job.
Good luck. If I were you, I had given that assignment to some young
programmer... ;-)
