Processes the CP SET command for general users.
Entry point for SET command processor. Pageable. Processes user's terminal options.
Entry paint for the TER!INAL command processor. Pageable. Saves pertinent data when a check point occurs.
Retrieves accounting data froll the VMBLOK, VDEVBLOK, and unpunched accounting cards. It
retrieves accounting information for dedicated
devices, saves the system log aessages, and saves
all control blocks for spool files. The data is
written on the SYSiAR! cylinder of the IPL pack. DMKCKP is loaded and executed by D!KD!P or
initial program load. Pageable. Performs checkpoint processing. Performs a checkpoint On any alterations in the
spool file set up to allow the recovery routine
to get them if warm start fails.
Initializes the check point cylinder after a
successful warm start from the standard recovery
procedure or after a cold start.
Recovers previously checkpointed spool file
information. This information includes all open
print or punch files in existence at the time the
system went down or was shutdown. All open spool
files are put in user hold status. Pageable. Determines if the clock should be synchronized. (Called from DMKCPI) Handles CLKCHK signal request.
Synchronizes the clocks.
Handles SYNC signal request.
Handles the TOD-sync-check external interrupt.
