No, there are not. > I don't see a clear statement of what the default is if one specifies, for > example, LOC=31. Is that equivalent to LOC=(31,31) or LOC=(31,64)? The book says: LOC=31 and LOC=(31,31) indicate that virtual and central storage can be located anywhere below 2 gigabytes. Jim Mulder z/OS System Test IBM Corp.
