SO (Set System Options)

Keyboard Input Message

Access Level: 8

The SO command sets (turns on) certain system options.

You can also set system options through the USE records of the system configuration file. See the V Series Systems Operations Guide Volume 1: Installation for more information.

You can reset (turn off) system options with the RO (Reset System Options) command or display the status of a system option with the TO (Display System Options Status) command.

<option name>
This specifies one or more of the system options described in the following Table.

Option Description
AFTR Automatically removes scheduled jobs that are after-linked to an abnormally terminated job
APBD Automatically prints and saves backup files after they are closed
APCR Automatically places pseudo card decks into pseudo card readers as the decks become present on disk or diskpack
AUHL Automatically initiates a halt/load in case of system failure
AURD Automatically removes pseudo card readers from disk if the files have erroneous control instructions
BOJ Displays Beginning-Of-Job (BOJ) messages each time a job enters the active mix
CHRG Specifies that all programs must have a charge number in order to execute
CLOS Displays a file-closed message each time a program closes a file
COPY Displays a message each time SYSTEM/COPY compares or transfers a file
DATE Requires a date to be entered in order to halt/load
DBUG Loads the interactive DEBUG module to trace the operating system or a user program
DCOM Loads a data comm module into memory when a data comm device is activated
DCP Loads a Data Communications Processor (DCP) into memory
DMS2 Loads the DMS2 extension module into memory
EOJ Displays an End-Of-Job (EOJ) message each time a program goes to an EOJ
GTDK Forces program trace requests to backup disk
ISC Allows programmatic use of the Inter-System Connect (ISC) for inter-system communications
LIB Displays a message each time a file is removed or changed
MICR Loads a reader-sorter module into memory
OPEN Displays a file open message each time a program opens a file
PBD Routes or directs printer backup files to disk
PBP Routes or directs printer backup files to diskpack
PBPS Directs all areas of printer and punch backup to a single diskpack
PBT Directs printer backup files to a scratch tape or a tape already in use for backup on a ready drive
PCD Indicates that punch card backup files are to be built on disk
PCH Directs punch files to the card punch without creating backup files
PCP Indicates that card backup files are to be routed to diskpack
PCRM Displays the location and contents of the first control card and each DATA(B) in a control card group as they are processed from pseudo card decks
PRN Directs printer files to the printer; no printer backup file is made
QWIK Loads the QWIK module, which causes user program overlays to be stored and retrieved from a memory buffer
RJE Enables the Remote Job Entry (RJE) handler to be executed when an RJE station becomes active
RMOV Resolves duplicate file conditions on disk or pack by indicating that the old file is to be removed
RTSL Indicates that short or long tape block reads that are not multiples of the logical record size are to be treated as I/O errors
SCHM Causes a message to be displayed each time a program is scheduled for execution
SNAP Produces a SNAP picture or “snapshot” to capture the state of memory when certain processor errors occur
STGO Indicates that a message is to be displayed whenever an executing program stopped (such as with the ST or STOP (Suspend Program Processing) command), or when the program is restarted (such as with the GO or START (Resume Stopped Program) command)
SYST Loads a module into memory in order to run FLAME
SYUP Executes the SYSUP program after a cold start or halt/load
TERM Terminates programs that have irrecoverable errors, otherwise they will go into a DS/DP condition.
TIME Requires that the time be entered before a cold start or a halt/load completes
TPLB Causes a message to be displayed each time a tape file becomes available
TPMK Saves all tapes containing non-rewound reels with a write ring in the event of a halt/load
TRAK Loads a TRAK module into memory and allocates a buffer for tracking information
TRMD Dumps jobs that terminate abnormally
WRKP Directs work files to unrestricted system resource diskpacks
ZIPM Displays the message ”<job ID> ZIP <control information message>” each time a program passes an instruction to the MCP


Setting the DBUG, DCOM, DCP, DMS2, MICR, QWIK, SYST and TRAK options causes the MCP to load an extension module into memory. These modules can be loaded at any time.

The RJE extension module is always loaded during system initialization because the MCP requires portions of it to handle Work Flow Language (WFL) programs. However, when you use SO to set the RJE option, the MCP enables the RJE-handling portions of the module and ensures that the DCOM module, which is also needed for RJE operations, is loaded as well.**



This sets the PRN option that causes print jobs to be printed so that no printer backup files need to be created.


This sets the TPLB option to have a message be displayed each time a tape file becomes available; sets the ZIPM option to have the message ”<job ID> ZIP <control information message>” displayed each time a program passes an instruction to the MCP; and sets the PBD option to route or direct printer backup files to disk.
