EOS, INTG, IO, IOCS, and PCI trace records

EOS records represent an end of sense interruption, INTG records represent an input/output (I/O) interruption that is used to signal the completion of a zHPF interrogate request, IO records represent an I/O interruption, IOCS records represent an I/O interruption that also contains concurrent sense information, for devices that support the concurrent sense facility, and PCI records a program-controlled interruption.

One of the following:
hhhhhhhh
Address of the address space control block (ASCB) for the address space that started the I/O operation.
