The CKPTREST macro is no longer used to define codes eligible for restart. Instead, use the following technique.

During system installation, your system programmer uses a standard IBM®® supplied list of system completion codes (codes produced when the system executes abend) to create the table of codes eligible for automatic restart. To change this table, the SYS1.PARMLIB member SCHEDxx RESTART/NORESTART statement type is specified. The RESTART statement type is used to add user-defined completion codes to the table of codes eligible for automatic restart. The NORESTART statement type is used to delete both IBM-supplied and user-defined codes from the table.
