Pageable.
Identifies a 2741 terminal as either a 2741P (PTTC/EBCD) or 2741C (correspondence) fro. the
user command. It sets ADEVTYPE the RDEVBLOK to TYP2741P or TYP2741C and sets flag RDEVIDNT on if
the terminal was successfully identified.
Pageable.
Contains the UCB buffer load images used by the LOAD command to load the universal character set
buffer in the 3811 control unit. This module
contains no executable code. Pageable. Contains the UCB buffer load images used by the LOAD command to load the universal character set
buffer in the 3203 printer control unit. This module does not contain executable code.
Pageable.
Contains the UCS buffer load images that the LOAD command uses to load the universal character set
buffer in the 2821 control unit. This module does
not contain executable code.
Pageable.
Allows the DMKDIRCT or DMKCPINT programs to build
a list of virtual page buffers; one for each UDIRBLOK page on disk.
Allows the DMKDIRCT program to swap the active
user directory to the newly created user
directory. Puts specified UDEVBLOK into the caller's buffer.
Finds a given user ID in the user directory and moves the user's directory entry into the
caller's buffer.
Reads the next user directory into the caller's
buffer.
Releases a virtual page used by the directory program as a buffer.
Pageable. Updates in-place the CP directory on the object DASD page and updates in-Flace the virtual system page (if used) on the Faging device. Entered
from DKKHVD when a class B virtual machine issues
a DIAGNOSE code '84' instruction.
Resident.
Untranslates CCWs and CSWs. Releases pages and free storage used for the CCW chain. Also processes the CP assist instruction, UNTFR (E605).
Finds the RCWTASKS that have been patched to
handle OS ISAM self-modifying sequences and put
them back the way DMKCCW had them to aIlew DMKUNTRN and DMKUNTFR to operate correctly. L- L--- ______________________ __

Attributes, Function
Translates a real CSW into
processes the CP assist
(E610) • a virtual CSi. Also
instruction, UBTRI Relocates sense byte information. For a 3330, 3340, 3350, or 2305, computes virtual cylinder
member in bytes 5 and 6 of the sense byte data by unrelocating the real cylinder number given by the hardware. For a 2311 simulated on a 2314 or
2319, computes the appropriate status for byte 3
of the sense data fro. the real sense data qiven
by the hardware. - Pageable. Processes user termination.
Processes the DISCONN (disconnect) command.
Logs off a user. Processes the FORCE command.
Returns subpools from the free storage chain and
removes spool file blocks and allocation blocks from the dynamic paging area.
Processes the LOGOFF command.
Resident.
Storage management for EC mode virtual machine. Allocates, initializes and maintains shadow,
segment, and page tables for virtual machines
that can relocate.
Returns active shadow tables to free storage. Services page or segment exceptions for virtual
EC machines. Virtual - virtual to virtual address translation.
Allocates and initializes shadow tables.
Handles pseudo page fault interruption from a VS1 virtual machine.
Processes paging exceptions for a virtual machine
that performs Virtual (shadow) virtual-to-real address
transla tion.
Processes segment exception for a virtual machine that performs paging.
Processes the CP assist instruction, ZAPPAGE (E60B) • Processes the CP assist instruction, ZAPSEGS (E60A) • Pageable.
Simulates I/O for a virtual cbannel-to-channel
adapter.
Selectively resets a device for a virtual
channel-to-channel adapter without decoupling the
CTCA from the I-side adapter.
Does a final reset for a virtual
channel-to-channel adapter and and disconnects
the adapter from its coupled twin on the I-side
virtual machine. CP Directories 1-253
