Attributes, Function
Generates informational messages for monitor
user. Opens monitor spool file, gets SFB, etc.
Schedules, via TRQBLOKs, requests to start and
stop monitor at specific times in the future. Writes a monitor data buffer to a spool file
buffer. Pageable. Changes the date in the system low storage at
midnight and resets the clock comparator for the
next midnight occurrence. DMKMID also sends messages to all users about the date change.
Pageable.
Constructs spool file header record.
Displays automatic monitoring information defined by SYSMON macro in DMKSYS. COMpletes monitor shutdown.
Initializes MONITOR shutdown: Handles monitor processing for SPOOL to USERID parmeters of START command.
Handles monitor tape header processing.
writes the MONITOR trailor record.
Pageable.
Processes commands and requests associated with
the MONITOR, including MONITOR CALL interruptions
within CP. Processes tape interruptions returned by DMKIOS. Processes a MONITOR CALL Frogram interruption.
Gets space for monitor record and manages
buffers.
Handles PERFORM (class zero) data collection
routine.
Handles USER (class four) data collection
routine.
Handle timer request interruptions. Pageable. Transmits messages to legged-on users for the MESSAGE, SMSG, or WARNING commands. Receives and
retransmits lines for the ECHO command for the
number of times specified. ECHO command processor. MESSAGE command processor. MSGNOH command processor. SMSG command processor. WARNING command processor.
Resident.
Allows system communication with the operator for
the enhancement of error recovery procedures.
Pageable.
Gets a 5-byte mnemonic opcode for a System/370 binary opcode • . ______ ______________________________________________________ __J CP Directories 1-243

synchronous lines and remote decoder. Dumps the 3705 network control program. Loads the 3705 network control program. These
routines may be called by a console command from DMKNET or or internally by DMKCPI (for LOID) or DMKRNH (for DUMP). Pageable. Dump the 3705 Network Control Program. Resident. Provides the necessary support for the VM/370 system console. Certain routines within the
control program cannot call DMKQCN to issue
writes to the system console. This module determines the system's primary console and
builds a channel program to handle the requested
call.
Resident.
Constructs IOBLOKs and schedules the tasks that move virtual storage pages between auxiliary
storage and main storage. It also calculates the
total system paging load at user-specified
intervals. Pageable. Sets a return code of zero in R2.
Resets the interruption.
Resets program event recording. Pageable. Release all the pages of a user's virtual storage from the real storage and from auxiliary storage
on the paging device.
Releases a specified part of virtual storage.
Calls DMKPTRPU to ensure that the user is not in
page wait and then releases the address range
contained in Rl through R2. It also unlocks any
pages that might have been locked.
