During session initiation, NPF checks the SLU's routing file record to see if a page format table entry name has been specified. Processing occurs as follows:

• If an entry name has been specified, the default page format data is copied from the named table entry. (If the named entry is not found, the session is rejected.)
• If the entry name is blank but the table contains an entry named DFLTNTRY, the default page format data is copied from that entry.
• If the entry name is blank and the table does not have an entry named DFLTNTRY, NPF uses hard-coded default page format values of MPP=80, MPL=1, LM=1, RM=80, TM=1, BM=1. (See EZAPPDPF for more information.)
