This is the error recording module. It receives
all requests for error recording and passes
control to the proper pageable routine after
checking if a recording is in progress. If a
previous request for error recording is in
progress, the current request is queued on the
appropriate queue for recording at a later time. It makes a check to determine if the recording
cylinder is full. DMKIOE also interfaces with the
pageable module that initializes and erases the
error recording cylinders.
Entry for a channel error condition occurring on
a SIO in DMKIOS with a response condition code of
one.
Entry for a stacked channel recording request
from the channel check handler.
Entry for a stacked channel check recording
request from ERP.
Entry point to locate the starting page record
for recording.
Entry to clear and format the recording area on
disk.
Entry for machine check recording.
Entry for a stacked machine check request.
Entry for a stacked environmental recording
request.
Entry for a stacked outboard error recording
request.
Calls to initiate error recording via DMKIOF (no DMKIOE function performed).

Processes a 3704/3705 and remote 3270 request.
Schedules recording for unit check, channel data
check, and hardware environmental counts.
Records 3330 data.
Schedules statistical data recording.
Schedules the update of a statistical data
request.
Processes an SVC 76 request.
Pageable.
Records system and I/O errors on the system disk
in predefined error recording cylinders.
Records channel check error from SIO in DMKIOS when cc=1.
Initializes pointers to available recording pages
at IPL and after an erase has been completed.
Records OBR and MDR records.

Attributes, Function
Pageable. Call~d at initialization to locate the error
recording device, locate the last outboard error
record and system recordings made on the
cylinders, and set the in-storage pointers to the
correct values. Initialization for RMS functions
is performed after first making a test to
determine if CP is running under CP. RMS functions are not activated for a virtual CP environment. This module also erases the
recording areas.
For 3031/3032/3033 processors, reads frames fro.
the SRF device, formats them in 4096-byte blocks,
and writes the records to the error recording
cylinders.
Contains all function of DMKIOG except erase.
Erases (1) error records or (2) error records and
frame records from the error recording cylinders,
depending on input parameters.
Resident. Schedules requests for virtual machine and program I/O operations, and services all I/O interruptions.
Halts an active device and drains all
interruptions.
Processes an I/O interruption. Schedules CP-generated I/O operation. Schedules a virtual machine I/O operation.
Processes the IOBLOK used for REWIND. Pageable.
Finds and modifies an ISAM CCW string.
Pageable.
Processes the QUERY command.
Processes the SET JOURNAL command. Processes LOGONs with invalid passwords. Processes LINKs which are successful.
Processes LINKs with invalid passwords.
Loader -utility program. Loads assembled program modules into storage at
locations other than those assigned by the
assembler. It completes linkage among the
modules and transfers control to one of the
loaded .odules for execution.
Pageable. Prollpts the user to enter a password, types
masking characters if appropriate, reads the
password from the terminal, and checks it for a
match.
Links to a virtual DASD because of an issued LINK cOllmand.
