Builds an account card buffer for a VDEVBLOK. creates account card buffer for a VMBLOK. Provides additional accounting function at logon
time (for installation use).
Punches queued up accounting cards.
Queues up account card buffers for output On a
real device.
creates a connect and usage ti.e .essage for a
user.
Pageable.
Handles the AUTOLOG command. Pageable.
This module is entered from DMKCPI only if in
attached processor mode. It is also entered fro. DMKCPU as part of the vary online processor
function.
Initializes the PSIs for each processor.
Initializes the control registers for the
attached processor. Pageable. Notifies the virtual machine that the coamand has
replaced the shared system with a private copy of
that shared system. The user continues to run
without the shared copy of the naaed system. Called by the co.mand processors via an SVC if
the command execution is to change a shared page.
Pageable.
Allocates storage for a virtual ECBLOK and the
two TRQBLOKs required for a virtual machine with
the ECKODE option# and initializes these blocks.
Releases real segment, page, and swap tables to
free storage.
Creates ana initializes seg.ent, page, and swap tables as a function of virtual storage size,
which is part of the process of building a user's
virtual aachine.
Creates and partially initializes a VKBLOK for a
virtual machine, identified by its terminal real
device block. Pageable. Provides the VK/370 or user logo (header) for
printed output.
Logo for initial screen display and header
separator for printer spool files.
Installation header reference. CP Directories 1-229

Attributes, Function
Resident.
Line error processing for remote 3270s on binary
synchronous lines only.
Examines the error condition resulting from a
unit check or channel error that occurred while
executing a CP-generated bisync line channel
program. If the error is uncorrectable, is
called to notify the operator. After return from DMKMSW, the original channel program is
terminated and the fatal flag is set in the IOBLOK. If the error is correctable, the channel
program is re-executed up to a maximum of seven
retries.
Resident.
Operates with the I/O interrupt handler to
schedule a device-dependent error recovery
procedure when a channel data check, control
check, or interface control check is detected.
Entry from DMKIOS when a channel check occurs
when storing a CSi after a SIO. Entry from DMKIOINT when a channel check occurs
on an I/O interrupt.
Reflects channel check information to the virtual machine. Entry from DMKIOE to allow error messages to be printed. Resident. CP assist TRANBRNG instruction (E60B). CP assist CCiGENRL instruction (E60F). CP assist TRANLOCK instruction (E609). through CP assist DECCi1 instruction (E60C). CP assist DECCWO instruction (E604). Invokes an internal subroutine (CNTRLSOB) to
obtain control bytes (seek data) • Searches previous (external) RCi chains and
resolves the address of the RCi task if found.
Takes the list of virtual CCis associated with
the user's SIO and translates it into a real CCW list.
Pageable.
Processes DISPLAY, DCP commands.
Executes the DISPLAY command to display real
storage locations.
Displays virtual storage locations, storage keys,
general registers, floating-point registers, PSi, CAW, and CSW at the terminal. _____ . ____ __________ _________ . ___________________________________________ --J 1-230 IBM VM/370 System Logic and Problem Determination--Volume 1
