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

Processes DUMP and DMCP commands.
Dumps real storage to spooled printer.
Dumps virtual storage to the spooled printer.
Dumps the contents of the specified real storage
locations on the virtual Frinter spool file.
Dumps the contents of the specified virtual
storage locations, registers, PSi, and storage
keys on the virtual printer spool file.
Pageable.
Processes STORE and STCP commands. Stores data into real storaae (STCP commandl. Stores data into virtual storage (STORE command) • Pageable.
Gets the address of the routine that processes
the CP console function that was requested.
Processes a CP console function.
Processes the SLEEP command.
Processes the BEGIN command.
Processes the QUERY command. Presents an attention interruption to the virtual
machine to simulate a real request key
interruption.
Pageable.
Processes LOCATE and ADSTOP commands. Stops virtual machine at specified address (ADSTOP command).
Displays address of real device blocks, or VMBLOK and/or virtual device blocks (LOCATE command).
Pageable.
Handles Diagnose code X'64'. Entry to IPL from LOGON (DMKLOG). Entry to IPL from a command line (DMKCFM). Pageable. Saves a virtual machine's storage space including
registers and PSi (SAVED System). Resident.
Processes DIAGNOSE code 8. It scans the command
line and goes to the required module. Posts an attention interrupt pending for the
virtual machine. Puts the terminal in console function (CP) mode (ATTN key pressed twice). Scans the command line
and goes to the command handling routine.
Entered when DIAGNOSE code 8 is executed. Scans the com.and line and goes to the command handling
routine .. CP Directories 1-231
