1Q44I JOB CANCELLED DUE TO READ DATA CHAINING xx
xx = BG/F4/F3/F2/F1
Cause: The supported partition (xx) has issued a CCW for a card reader with the data chain
bit on (bit 0 in byte 4 of the CCW). POWER does not support read data chaining.
System Action: The job is canceled with a program check forced by POWER in the partition
xx and a dump is spooled to the print queue for this iob. The program check address points to
the second byte of the SVC 0 (0A00) which caused the problem and register 1 in the dump
points to the CCB on which the SVC 0 was issued.
Programmer Action: This job can be executed only without POWER or under a POWER
writer-only system. or it should be modified so that read data chaining is not necessary.
Operator Action: none.
