How to define the disposition (DISP) for the Finalist SEEDLOG dataset on the z/OS platform

Operating System: z/OS
Products Affected:  Finalist
For z/OS, the Finalist Installation Guide states that the SEEDLOG should be defined as follows in a z/OS environment:

// SPACE=(TRK,(1,1),RLSE

However, if enqueue/contention problems arise when multiple jobs exist, we recommend the SEEDLOG be defined with a DISP of NEW,CATLG. When defined as NEW,CATLG, each job will create its own unique SEEDLOG so should the file ever get populated, there might be multiple SEEDLOG's that would need to be processed.
