Meets the CP nucleus residency requirements for TRQBLOK and CPEXBLOK entries to pageable VK Monitor module DMKMIA. Used to invoke a MONITOR STOP command via a CPEXBLOK. Used to invoke a MONITOR STOP com.and via a TRQBLOK request. Used to complete monitor shutdown processing, via CPEXBLOK. Used to invoke a MONITOR CLOSE command via a CPEXBLOK. Used to invoke a MONITOR START SPOOL command via
a CPEXBLOK. Used to invoke a MONITOR START SPOOL command via
a TRQBLOK request.
High frequency I/O status sampling routine,
entered every two seconds via TRQBLOK request. DASTAP class 6 code 2 I/O status sampling routine, called from DMKMONTI every 60 seconds to
collect the data accumulated by DMKENTTI. Pageable.
This is the message writer. Locates the
requested message and inserts the module ID, message number, and data. It also prints the message. Resident
Handles all SIGNAL actions after CP initialization.
Entry point for External Interrupt handler
Pageable.
Contains the foras control load buffer images
that the LOADBUF command uses to load the forms control buffer in the 3811 control unit for the
3203 or 3211 printer. The LOADVFCB command also
uses DMKFCB to load the forms control buffer in
the virtual 3203 or 3211 printer. Standalone program. Initial program loaded or run under CMS if on a CMS disk. Adapts parameters from the console or IPL device (card reader) and per forms partial or
complete formatting, allocating, and labeling of
2314, 2319, 3330, 3340, 3350 and 2305 DASD devices. The FORMAT program also write-checks the
surfaces. Bad surfaces are flagged to prevent
their use. No alternative tracks are assigned. OS labels are written to be compatible with OS, but
labels indicate to OS that no space is left on
the DASD device. All input parameters are
verified for correctness.

Free storage manager.
Gets space from free storage and processes the CP assist FREE instruction (E600). Special entry point to acquire free storage. If
the storage request cannot be satisfied, a
condition code of one is returned to the caller.
Returns subpools to free storage chain.
Returns space to free storage and processes the CP assist FRET instruction (E601). Returns space to free storage; does not release
pages. Pageable. Initializes supervisor operations for tape, unit
record, and nonstandard disk I/O operations.
Checks device validity and initializes I/O operations on tape, unit record, and nonstandard
disk I/O programs per supervisor call. This module presents resultant condition code and CSW (if warranted) to the user.
