Entered by a KXCHK macro tc halt execution after HX has
been entered after signaling attention.
Entered by any routine that sets up ABNPSW and AENREGS in the work area beforehand.
Entered as the result of a DMS!BN TYPCALL=SVC macro call.
Returns entry point from tEBUG. Accesses data in the ADT and related information (such
as AFT's and chain links) in virtual storage.
Reads all file status table blocks into storage for a
read/write disk. Reads in file management tables for a
read -only disk. For an O/S disk, control returns to
to the caller after a successful return from DMSACM. Reads the ADT, QMSK, QQMSK, and first chain link into
virtual storage from the master file directory cn disk.
For a specified disk, releases all tables kept in free
storage and clears appropriate information in the
active disk table (ADT).
Provides an interface to DOS Access
programs (IDCAMS). Provided for support Method Utility
of CMS/VSAM. Provides storage for the ASM3705 assembler auxiliary
directory. DMSARD contains no executable code. It must be loaded with DMSARX and the GENDIRT command must then
be issued to fill in the auxiliary directory entries. GENMOD must then be issued to create the ASSEMBLE 1I0dule. Releases storage used for tables pertaining to a given
disk when that disk is no longer needed.
This is the ASM3705 command processor. It provides the
interface between user and the 370x Assembler.
This is the SISUT2 processing routine called from DMSSOB and used during the assembly whenever any I/O activity pertains to the SYSUT2 file. Provide an interface for the ASM3705 command to the 3705 assembler program.
Provides storage for the assembler auxiliary directory. DMSASD contains no executable code. It must be loaded
with DMSASM and the GENDIRT command must then be issued
to fill in the aUXiliary directory entries. The GENMOD co •• and must then be issued to create the assemble module. CMS Directories 2-157

This is the SYSUT1 precessing routine (called from DMSSOB) • Associates logical units with a physical hardware
device. (Interface for the ASSGN command used by CKS/DOS and CMS/VSAM.) Reserves space on disk for writing a copy of disk and
and file management tables on disk and then updates the
master file Closes all eMS files, thereby updating the master file
Directory for any disks that had an output file open.
Give control to an abnormal termination routine once linkage to such a routine has been established ty STXlT AB lIacro. Opens CMS/DOS files associated with the following DTF
(Define The File) tables: DTFCN, DTFCD, DTFPR, DTFMT, DTFDI, DTFCP, DTFSD. Once the files are opened and
initialized, I/O operations can be performed using the
file.
Reads one or more Ruccessive itells froll a specified
file. Processes the BASIC command. The BASIC command invokes
the CALL-OS BASIC language processor to coaFile and
execute the specified file of BASIC source code.
This is the CMS batch bootstrap routine. It loads the
batch processor routine (DMSBTP) and user exit routine
(if they exist) into free storage. Main entry; reads from the virtual card reader each time CKS tries to execute a console read.
Entry point for abnormal conditions during user job: • Job exectuion ABEND (from DKSABN) • Job liait exceeded (froa DftSITE, DMSCIO, DMSPIO) • Disabled CMS command (from the comlland) Non-executable user job limit table referenced by DKSITE, DMSPIO, and DMSCIO. Writes one or more successive items into a specified
disk file. Stacks a line of console input that DftSCRD reads later
when it is called.
Reads one card record.
Punches one card record.
Punch caller's buffer.
