Function
Processes the interrupticns for all CMS terminal I/O operations and starts the next I/O operation upon
completion of the current I/O operation.
Processes terminal interruptions.
starts next terminal I/O operation.
Frees I/O buffers from stacks. Closes CMS/DOS files associated with the following DTF
(Define The File) tables: DMTCN, DTFCD, DTFPR, DTFMT, DTFDI, DTFCP, and DTFSD. For reader, printer, or punch
files, a CP CLOSE command is issued. For disk files, DMSFNS is called to close the file. For a disk work
file, DMSERS is called to erase the file, unless
DELETFL=NO is specified. Compares the records contained in two disk files. Passes a command line tc CP for execution.
Processes the COPYFILE command to copy disk files.
Reads an input line and makes it available to the
caller • • rites an output line to the console. Causes the calling program to wait until all terminal I/O operations have been completed.
Enables a user to dump his virtual storage from within
an executing program.
Enables the user to debug his program from the terminal. Entry point for program interruptions. Entry point for all other interruptions.
Reads one or more SOO-byte records (blocks) from disk,
or reads one 200-byte record (sut-block) from disk. Writes one or more 800-byte records (blocks) on disk,
or writes one 200-byte record (subblock) on disk.
Interface for the DOS DLBL command; allows the user to
specify I/O devices extents, and certain file
attributes for use by a program at execution time. DLBL can also be used to modify or delete proviously
defined disk file descriptions.
Interface for the DOS user command. Link-edit the
relocatable output of the language processors. Once link-edited, these core image phases are added to the
end of the specified DOSLIB. Simulates the DOS/VS $$BDU8P and $$BPDC8P For both functions* a CP DUMF command
