`
`

`

`CMS PERFORMANCE ENHANCEMENT
`
`The discontiguous saved segment, CMSSEG, has been removed by merging
`modules from the CMSSEG segment into the CMS shared nucleus.
`
`DIAGNOSE ‘14’
`
`_
`DIAGNOSE X‘14’ has been modified so that subcodes X‘OFFE’ and
`X‘OFFF’ respect the SFBINUSE flag when the file is not in use by the reader.
`These subcodes wait for a file being used by a system function. If, however,
`the file is not available within the 25-milliseccnd time limit a condition code of
`
`3 and a return code of 24 is returned. This condition shows system problems
`because of performance or errors in the spoofing area.
`
`4245 LINE PRIMER SUPPORT
`
`The 4245 Line Printer is a channel-attached, high-speed line printer (2000
`LPM) using print band technology. It combines 3203 and 3262 technologies
`with newly developed hardware. The programming support for this printer is
`similar to the 3262 programming support. The 4245 is supported as a virtual,
`dedicated, and system printer. In addition, FCB lengths for the 4245 will be
`allowed the maximum length that hardware supports (256 byte length). It is
`not limited to a ISO-byte maximum length as are previous printers.
`
`3088 MULTISYSTEM CHANNEL COMMUNICA TI0N3 UNIT
`
`The IBM 3088 Multisystem Channel Conununications Unit interconnects
`multiple systems using block multiplexer channels. The 3088 uses an unshared
`subchannel for each unique address and is fully compatible with existing
`channel-to—channel adapter protocol.
`
`VM/SP 3800 MODEL 3 COMPATIBILITY
`
`VM users have access to the 3800 Model 1 and Model 3 Printing Subsystem.
`Existing programs designed to produce 3800 Model 1 printer output may
`produce output for the 3800 Model 3 printer with little or no program change.
`
`Use of this support provides improved print quality (240 X 240 pel resolution
`compared with the 180 X 144 pel resolution of the 3800 Model 1) and the
`addition of a 10 lines-per-inch (LPI) vertical space option.

`
`PR OGRAMMA BLE OPERA TOR FA CILITY
`
`This facility provides the capability to: log messages, suppress messages,
`redirect messages, execute messages, or preprogram message'responses. The
`capabilities are under control of an editable message routine table in a CMS
`file.
`
`Inter-User Communication Vehicle (IUCV) enhancements for message
`handling are also included.
`
`DIAL COMMAND SUPPORTFOR REMOTE BSC 32 70 USERS
`
`This facility provides the ability for remote BSC 3270 users to issue the DIAL
`command. The remote 3270 appears to be a locally attached terminal to the
`dialed virtual machine.
`
`ENHANCED 3800 SUPPORT
`
`This facility allows the RSCS Networking Release 3 program product to pass to
`CF the 3800 attributes defined in a NJI header created by a system using the
`Network Job Interface (NII) protocol. This will also allow files created in
`these systems to print properly on a 3800 controlled by VM/ SP Release 2.
`Copy group and burst attributes remain unsupported.
`
`COMMAND RETRIEVE CAPABILITY
`
`A RETRIEVE option is added to the CP SET program function command.
`When specified, the system will save input lines. When the specified program
`function key is pressed, the saved input lines are redisplayed in the reverse
`sequence of entry.
`
`QUER Y COMMAND ENHANCEMENT
`
`The QUERY command is enhanced to allow the user to specify the operands
`“USERID” or “CPLEVEL.” The QUERY USERID command responds with
`the userid and with the system identifier of the system that the user is logged
`on to. The QUERY CPLEVEL command provides information relative to the
`software product’s name (e.g. VM/SP). release number, service level number,
`nucleus creation date and time, along with the .[PL date and time. Time zone
`information is also included.

`Vi VM/SP CP Command Reference for General Users
`
`

`

`Preface
`
`This publication is a reference manual that discusses the IBM-Defined Class G
`VM / SP CP commands available to the general user.
`
`The user should be knowledgeable of the concepts of VM/SP as outlined in the
`Virtual Machine/System Product Introduction, Order No. 6019-6200. In addition,
`the user should be aware of the logon process, terminal-initiated interrupts,
`terminal modes, and the method of switching from GP to virtual machine mode and
`vice versa. This information is detailed in the Virtual Machine /’System Product
`Terminus! Reference. Order No. (3019-6206.
`
`With the commands described in this publication, the general user can reconfigure
`his virtual machine, control devices attached to his virtual machine, perform input
`and output spoofing functions, and simulate many other functions of a real
`computer console.
`
`Other VM/ SP CP commands, available only to system operators, system
`programmers and analysts, and service representatives, are described in the
`publication Virtual Machine/Swen: Product Operator’s Guide, Order No.
`SCl9-6202.
`

`XViii VM/ SP CP Command Reference for General Users
`
`

`

`Part 1. Guidance Information
`
`N
`
`This part of the publication contains general information about the Virtual
`Machine/ System Product (abbreviated VM/ SP) system. It contains three sections.
`
`“The CP Command Syntax” describes the CP command environments and the
`general structure of the command languages.
`
`“The CP Command Language" provides additional information on the CP
`command set.
`
`“CP Command Usage” describes a variety of user requests Via class G CP
`commands.

`
`

`

`The CP Command Syntax
`
`The CP component of VM/ SP has its own command language. Much like any
`other language, the CP command language has a set 3 rules and structures. This
`section describes the CP command language environment, syntax and structure,
`giving general descriptions of command names, operands and their position on the
`command line, and character set usage in OF. A further discussion of CP
`commands is included in VM/SP Operating System in a Virma! Machine.
`
`There are two types of CP commands: system commands and user—defined
`commands. Depending on your privilege class, you can issue CP system commands
`to do various system oriented functions. Privilege class is discussed in “Section 2.
`The CP Command Language.” You, as a class G, or general, user can use CP
`commands to simulate the function of the system operator’s console. You can issue
`commands to control the operating system running in your virtual machine much
`like an operator controls the entire VM/ SP operating system using the keys and
`switches on his system console. User—defined CP commands are aIIOWed, too;
`however, your system programmer must create them for you. The procedure for
`creating your own CP commands is detailed in I’M/SP System Programmr’s
`Guide.
`
`VM/SP Command Environments
`
`There are two basic command environments: the control program (CP) command
`environment and the virtual machine command environment.
`
`You are in the control program (CP) command environment when you log on to
`VM/ SP and issue CP commands.
`
`You are in the virtual machine command environment when you load your virtual
`machine with CMS or another operating system.
`
`If you are operating under CMS, you can determine which command environment
`you are in by entering a null line (that is, pressing the enter key, or equivalent, with
`no data). VM/SP responds to a null line by displaying the current command
`environment, CMS or CF.

`The CP Command Syntax
`
`VM/ SP CP Command Structure
`
`A VM/SP command consists of a command name, usually followed by one or more
`positional operands. The general form for the CP command line is:
`
`
`
`You must use one or more blanks to separate each entry in the command line
`unless otherwise indicated.
`
`The Command Name
`
`The command name is an alphameric symbol of not more than eight characters. In
`general, the names are verbs that describe the function you want the system to
`perform. For example, you may want to find out whether or not a certain user is
`logged on the VM/SP system. In this case, you would use the CP QUERY
`command.
`
`The Command Operands
`
`The command operands are keywords and positional operands of no more than
`eight alphameric characters each. The operands specify the information on which
`the system operates when it performs the command function. For the QUERY
`command, for example, you could use the USER or userid operand to find out
`whether the user is on the system.
`
`Some commands require no operands; others require several. You can find each
`class G and class Any command with all of its operand requirements in “Section 5:
`Format of CP Commands” of this publication.
`
`You must write the operands in the order in which they appear in the command
`formats in Section 5, unless otherwise specified.
`
`Comments In the CP Command Language
`
`You can write comments with CP commands of the following types:
`
`. Commands with no operands
`- Commands with a fixed number of operands
`. Commands with a single optional operand
`
`You should not write comments with commands that have a variable number of
`
`operands or with commands that have more than one optional operand. If you do,
`the comment could be interpreted as an operand.
`
`You can enter comments on your console by using the CP * command.

`
`Character Set Usage
`
`VM/SP commands are entered using a combination of characters from six different
`character sets. The contents of each of the character sets is described in Figure 1.

`6 VM/ SP CP Command Reference for General Users
`
`

`

`The CP Command Language
`
`The CP commands represent a set of interactive console functions that are used (1)
`by the operator to control the VM/SP system and (2) by a user to control a virtual
`machine.
`In this publication, only those commands that are used to control a
`virtual machine are fully documented. Other commands are referenced only to the
`extent necessary to show relationships and provide general knowledge.
`
`Privilege Classes for CP Commands
`
`Each user of VM/ SP is assigned one or more privilege classes as part of the
`directory entry of the virtual machine. Each user class is indicative of a specific
`function of a virtual machine and entitles the user to a specific subset of the CP
`command language.
`
`Your installation may add to, or delete from, this set of commands in order to tailor
`the command set to your needs. Your installation administrator should make you
`aware of any changes of this type.
`
`If your installation chooses to change user classes, you may record the changes in
`the blank column in Appendix A, Command Summary, in the back of the book.
`
`This publication is a reference manual for class G and class ANY subsets of the CP
`command language.
`
`Figure 2 on page 8 lists each CP privilege class along with the associated type of
`user and function performed. Figure 2 on page 8 also identifies the specific
`publications in which each class subset of CP commands is described in detail.
`
`For a complete list of CP commands grouped by privilege class, refer to VM/SP
`Operators Guide.
`
`Although users are functionally divided into seven classes (A through G) with a
`corresponding privilege class of CP commands, there is another small group of
`commands available to all users. The eighth group consists of commands that do
`not belong to a privilege class because they are used to perform certain basic
`functions that are required by all virtual machines, such as logging on, logging off,
`and sending messages. These CP commands are in class Any.
