Maximum number of batch jobs

I think that this is a very simple query but I can not find the information anywhere.

In EnterpriseOne 8.9 batch queues are defined using P986130.

Does anyone know, if you do not specify a maximum number of batch jobs is a blank read as being one or many (infinity) ?

Any information would be helpful

Thanks

'0' (zero) means to allow any number to run. Since the queue can be disabled by making it not active (NA vs. AV), this makes sense.
