April 1, 1981 4. The value of the RDEVTYPC field (displacement X'06'; describes the
device type class and the value of the RDEVTYPE field (displacement describes the device type. Refer to Figure 10 for the list
of possible device type class and device type values.
5. The RDEVAIOB field (displacement X'2ij') contains the address of the
active IOBLOK. 6. The RDEVUSER field (displacement X'2S') points to the VMBLOK for a
dedicated user.
7. The RDEVATT field (displacement X'2C') contains the attached vit:'tual address. S. The RDEVIOER field (displacement X'4S') contains the address of the IOERBLOK for the last CP error.
9. Fot:' spooling unit record devices, the RDEVSPL field (displacement X'1S') points to the active RSPLCTL block. 10. Fot:' real 370X Communications Controllers, several pointer fields
are defined. The RDEVEPDV field (displacement X'1C') points to the
start of the free RDEVBLOK list for EP lines. The RDEVNICL field
(displacement X'3S') points to the network control list and the RDEVCKPT field (displacement X'3C') points to the CKPBLOK for
re-enable. Also, the RDEVMAX field (displacement X'2E') is the
hiqhest valid NCP resource name and the RDEVNCP field (displacement X'30') is the reference name of the active 3705 NCP. 11.
