Attributes, Function Process new virtual PSi and dispatch. Entered if
the virtual PSi has been entered outside of DMKDSP. Main entry point. Updates timers and dispatches
user. CP assist DSPO instruction (E60D). CP assist DSP1 instruction (E607). CP assist DSP2 instruction (E611). Processes interrupt from virtual interval timer. Nonexecutable; dispatched user's maximum time
slice.
Queues anchor for IOBLOKs and CPEXBLOKs. Entered attached processor mode when the
system lock is not held.
Number of dynamically assignable page frames now available in the system. Pageable. Analyzes the 2880 channel logout and sets
appropriate bits in the ECSi field according to
the results of this analysis. It moves the
channel logout to the channel check record. Pageable. Contains the framework of the common error
messages that are generated at various places
within CP. Module DMKERM references DMKEMA to
write error messages that require variable data
to be inserted into them. This module contains
no executable code and contains all error
messages from 0 to 169. Pageable. Contains the framework for the common error
messages that are generated at various places
within CP. The module DMKERM references DMKEMB to write error messages that require variable data
to be inserted into them. This module contains
no executable code and contains all error
messages from 170 to 423. Pageable. Contains the framework of the common error
messages that are generated at various places
within CP. Module DMKERM references DKKEMC to
write error messages that require variable data
to be inserted into them. This module contains
no executable code and contains error messages 424 and up. CP Directories 1-237

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.
