When an input record that contains a channel 2 carriage control is read (or when previous input records have been printed with previous PRINTLINEs and this is the next PRINTLINE to be processed), the first data byte (after the carriage control byte) is tested. Since the >=x'00' condition is always true, the current COPYGROUP (from the FORMDEF) is >used (NULL) for the next page, but the P2 PAGEFORMAT is used to format the next page.
See Chapter 6. Conditional Processing in the PPFA book for a more detailed explanation. By the way, the current PPFA book is S544-5284-09.
