I think those are arbitrary limits, for the purpose of preventing an errant program or user from using too many address spaces, and also for allocating the storage for the table which is used to keep track of these address spaces. Do you have a scenario where these limits would be too low for your installation's intended use of this function? Jim Mulder z/OS System Test IBM Corp.
