This command connects the user's terminal to the password-protected service PURSE. The password is BEOR.

Allows you to log in to a remote host over a TCP/IP connection and start an interactive terminal session by accessing the RLOGIN application.

Format

Parameter

IPhostname

Specifies the IP host name of the remote host.

IPaddress

Specifies an IP address of the remote host.

Description

The SET HOST/RLOGIN command allows you to log in to a remote host by invoking RLOGIN client software that runs on your system. Once you start the terminal session, you can enter commands interactively on the remote host. The parameter that specifies the remote host is either an IP host name or an IP address.

Qualifiers

/AUTHENTICATE

Specifies that Kerberos authentication should be used for acquiring access to the remote node.

/PASSWORD=password

Optional qualifier that specifies the password of the user logging in to the remote host.

/TERMINAL_TYPE=type

Sets the terminal emulator to one of the following terminal types: VT100, VT200, VT300, VT400, VT500.

/TRUNCATE_USERNAME

Specifies that the current user name should be truncated to 8 characters before attempting to connect to the remote node. The qualifier is required for communication with systems that limit the size of their login names to 8 characters. The /TRUNCATE_USERNAME qualifier is ignored if /USERNAME is specified.

/USERNAME=username

Specifies the user name for logging in to the remote node. The user name can be enclosed in quotes to preserve the case of the user name for case sensitive systems such as UNIX systems. If the /USERNAME qualifier is not specified, the default is the current user's user name.

Example

$ SET HOST/RLOGIN remotehst1
      

This example creates an RLOGIN connection to remote host remotehst1 over a TCP/IP connection.

Connects you to a remote host over a TCP/IP connection by invoking the TELNET application.

Format

Parameter

IPhostname

Specifies the IP host name of the remote host.

IPaddress

Specifies an IP address of the remote host.

Description

The SET HOST/TELNET command allows you to connect to a server on a remote system by invoking the TELNET client software that runs on your system. The parameter that specifies the remote host is either an IP host name or an IP address. Most of the attributes are negotiated with the remote node. The qualifiers are used only in exception cases (for example, cases where a remote server does not support a negotiated parameter but requires a certain characteristic for the connection).

Qualifiers

/AUTHENTICATE

Specifies that Kerberos authentication should be used for acquiring access to the remote node.

/PORT=port

Specifies the remote TCP port to use. The default is 23.

/TERMINAL_TYPE=type

Sets the terminal emulator to one of the following terminal types: VT100, VT200, VT300, VT400, VT500.

Example

$ SET HOST/TELNET remotehst2
      

This example creates a TELNET connection to remote host remotehst2 over a TCP/IP connection.

Connects you to a remote IBM host over a TCP/IP connection, causing the local keyboard to emulate an IBM 3279-class terminal keyboard by invoking the TN3270 terminal emulator.

Format

Parameter

IPhostname

Specifies the IP host name of the remote host.

IPaddress

Specifies an IP address of the remote host.

Description

The SET HOST/TN3270 command allows you to connect with a TELNET server on a remote IBM system by invoking the TN3270 terminal emulator TELNET client program on the local host. The parameter that specifies the remote host is either an IP host name or an IP address. The TN3270 client will automatically determine the terminal type (IBM-3278-2, IBM-3278-3, IBM-3278-4, or IBM-32798-5).

Qualifiers

/AUTHENTICATE

Specifies that Kerberos authentication should be used for acquiring access to the remote node.

/PORT=port

Specifies the remote TCP port to use. The default is 23.

/TERMINAL_TYPE

Sets the terminal emulator to one of the following terminal types: VT100, VT200, VT300, VT400, VT500.

Example

$ SET HOST/TN3270 remotehst3
      

This example creates a connection to a TELNET server on the remote IBM system remotehst3 over a TCP/IP connection.

Sets and locks the key definition state for keys defined with the DEFINE/KEY command.

Format

SET KEY

Description

When you define keypad keys using the DEFINE/KEY command, you can assign a specific state name to the key definition. If that state is not set when you press the key, the definition is not processed. Use the SET KEY command to change the current state to the appropriate state.

Qualifiers

/LOG (default)

/NOLOG

Controls whether the system displays a message indicating that the key state has been set.

/STATE=state-name

/NOSTATE

Specifies the name of the state. The state name can be any alphanumeric string. If you omit the /STATE qualifier or use the /NOSTATE qualifier, the current state is left unchanged. The default state is DEFAULT.

Example

$ SET KEY /STATE=EDITING
      

The SET KEY command in this example sets the key state to the state EDITING. You can now use the key definitions that were defined for the state EDITING.

Sets the interactive limit (number of interactive users allowed on the system), or displays the interactive limit and the current number of interactive users.

Requires OPER (operator) privilege to set the login limit.

Format

SET LOGINS

Parameters

None.

Description

The SET LOGINS command is not retroactive. All users logged in to the system before you enter the SET LOGINS command are not affected by the command; however, once the limit you set is reached, no more users can log in to the system until someone else logs out. Users with the OPER privilege are not affected by the limit.

If you do not specify a parameter value with the /INTERACTIVE=n qualifier, the SET LOGINS command displays the following information:

Login quotas - Interactive limit=x, Current interactive value=y

The value x represents the current interactive limit, and the value y represents the number of users currently logged in to the system.

Qualifier

/INTERACTIVE[=n]

Establishes the number of interactive users allowed to gain access to the system. If the parameter n is specified, the interactive limit is set to the value n. If the parameter n is not specified, the SET LOGINS command displays the current interactive limit and the number of interactive users.

Examples

$ SET LOGINS/INTERACTIVE=5
%SET-I-INTSET, login interactive limit=5, current interactive value=3
      

In this example, the SET LOGINS command specifies that only five interactive users can be logged in to the system.

$ SET LOGINS/INTERACTIVE
%SET-I-INTSET, login interactive limit=9, current interactive value=6
      

When the SET LOGINS command is entered without a parameter, as shown in this example, the /INTERACTIVE qualifier requests that the current status of the login quotas be displayed. The message returned indicates that the maximum number of interactive users allowed on the system is 9 and that the number of interactive users currently logged in is 6. No change is made.

Defines the default characteristics associated with a specific magnetic tape device for subsequent file operations.

The SET MAGTAPE command is valid for magnetic tape devices mounted with foreign volumes.

Format

SET MAGTAPE device-name[:]

Parameter

device-name[:]

Specifies the name of the magnetic tape device for which the characteristics are to be set. The device must not be currently allocated to any other user.

Qualifiers

/DENSITY=density-value

Specifies the default density for all write operations on the magnetic tape device when the volume is mounted as a foreign tape or as an unlabeled tape.

Valid density values are:

Keyword	Meaning
DEFAULT	Default density
800	NRZI 800 bits per inch (BPI)
1600	PE 1600 BPI
6250	GRC 6250 BPI

/END_OF_FILE

Writes a tape mark at the current position on the magnetic tape volume.

/FAST_SKIP=option

Allows you to skip by file mark or by record.

Note This tape positioning qualifier is for use on local SCSI tape drives only.

PER_IO (default)	Allows a local MK device to use the skip-by-filemarks function. The tape drive must be able to do a SCSI READ POSITION command and report blank check at end-of-data. The IO$M_ALLOWFAST function modifier must be supplied with IO$_SKIPFILE. Otherwise, the tape will skip files using the skip-by-records function.
ALWAYS	Allows a local MK device to use the skip-by-filemarks function. The tape drive must be able to support the skip-by-filemarks function, and no modifications should be needed to the IO$_SKIPFILE function.
NEVER	Specifies that a local MK device skip only by records. If you use a utility that depends on the semantics of skipping with skip-records, you may also need to use this option because it causes BACKUP or COPY to use the previous positioning.

/LOG

/NOLOG

Displays information about the operations performed on the magnetic tape volume.

/LOGSOFT (default)

/NOLOGSOFT

Controls whether soft errors on the specified device are to be logged in the error log file. Soft errors are errors corrected by the hardware without software intervention. This qualifier affects only devices that support hardware error correction, such as the TU78 magnetic tape drive. When used with other devices, this qualifier has no effect.

/MEDIA_FORMAT=[NO]COMPACTION

Controls whether data records are automatically compacted and blocked together on a TA90E tape drive. Data compaction and record blocking increase the amount of data that can be stored on a single tape cartridge.

Note that once data compaction or noncompaction has been selected for a given cartridge, that same status applies to the entire cartridge.

/RETENSION

Moves a TZK10 tape cartridge to the end of the tape, and then back to the beginning of the tape. Use the /RETENSION qualifier on a regular basis to help maintain the integrity of TZK10 tape cartridges.

The /RETENSION qualifier must be used in conjunction with the /REWIND or /UNLOAD qualifier. The /RETENSION qualifier completes its action before /REWIND or /UNLOAD. Use /RETENSION/REWIND when you want the tape cartridge to remain loaded in the drive. Use /RETENSION/UNLOAD when you want to unload the tape cartridge after the retension operation.

This qualifier only affects TZK10 tape cartridge drives and has no effect on non-SCSI drives.

/REWIND

Requests that the volume on the specified device be rewound to the beginning of the magnetic tape.

/SKIP=option

Requests that the magnetic tape volume be positioned according to any of the following options:

BLOCK: n	Skips the specified number of blocks.
END_OF_TAPE	Positions the volume at the end-of-tape (EOT) mark.
FILES: n	Skips the specified number of tape marks (not files). The tape is positioned just past the nth tape mark. If n is negative, the tape is still positioned after the nth tape mark, not before it. If the tape is already positioned immediately after a tape mark, a skip of -1 results in no net movement. (The tape moves to the preceding mark, but is then repositioned to the end of the mark, where it began.) For more information on tape marks and files, refer to the OpenVMS System Manager's Manual.
RECORD: n	Skips the specified number of records up to 32767.

/UNLOAD

Requests that the volume on the specified device be rewound and unloaded.

Examples

$ MOUNT MTB1:/FOREIGN
$ SET MAGTAPE MTB1: /DENSITY=800
      

The MOUNT command in this example mounts a foreign tape on the device MTB1. The SET MAGTAPE command defines the density for writing the magnetic tape at 800 bpi.

$ MOUNT MTA0:/FOREIGN
$ SET MAGTAPE MTA0:/SKIP=FILES:4
      

The MOUNT command in this example mounts a foreign tape on the device MTA0; the SET MAGTAPE command directs the magnetic tape position to skip four files.

Sets the format for system messages or specifies a process level message file. Lets you override or supplement the system messages.

Format

SET MESSAGE [filespec]

Parameter

filespec

Specifies the name of the process level message file. Messages in this file supersede messages for the same conditions in the system message file or in an existing process message file. The file type defaults to .EXE. The asterisk (*) and the percent sign (%) wildcard characters are not allowed. If you do not specify this parameter, the qualifiers apply to the system message file.

Description

The SET MESSAGE command specifies which message fields the OpenVMS system displays. The message format is as follows:

%FACILITY-L-IDENT, text

When a process is created, the default is to display all four message fields: facility, severity, identification, and text. To control which fields of a message are displayed, specify the appropriate qualifiers. For example, to omit the FACILITY field in message displays, specify SET MESSAGE /NOFACILITY.

By including the SET MESSAGE command in your login command file, you can select specific portions of the messages for your process.

Use the SET MESSAGE command, also, to override or supplement system messages. Whenever any software detects an error and invokes the $GETMSG system service, the message files are searched in the following order: image message sections first, process-permanent message files second, and the system message file last. Thus, with the SET MESSAGE command, you can introduce messages earlier in the searching order; you can either override or supplement the system messages. (Note that the new message definitions affect only your process.)

If a process-permanent message file exists when you specify the SET MESSAGE command with a file specification, the old file is removed and the new file is added.

The message definitions you specify must result from a successful compilation with the MESSAGE command. For full details on how to create your own messages with the Message utility, refer to the OpenVMS Command Definition, Librarian, and Message Utilities Manual.

Qualifiers

/DELETE

Removes any process-permanent message files currently in effect. Do not specify the filespec parameter with the /DELETE qualifier.

/FACILITY (default)

/NOFACILITY

Formats messages so that the facility name prefix appears.

/IDENTIFICATION (default)

/NOIDENTIFICATION

Formats messages so that the message identification prefix appears.

/SEVERITY (default)

/NOSEVERITY

Formats messages so that the severity level appears.

/TEXT (default)

/NOTEXT

Formats messages so that the message text appears.

Examples

$ TYPE XXX
%TYPE-W-OPENIN, error opening DB1:[MARSHALL]XXX.LIS; as input
-RMS-E-FNF, file not found
   .
   .
   .
$  SET MESSAGE/NOIDENTIFICATION
   .
   .
   .
$ TYPE XXX
%TYPE-W, error opening DB1:[MARSHALL]XXX.LIS; as input
-RMS-E, file not found
      

When the first TYPE command is entered in this example, the error messages include all fields. Later, the SET MESSAGE command establishes that the IDENT portion (the abbreviation for the message text) is omitted in future messages.

$ SET MESSAGE NEWMSG
      

The SET MESSAGE command in this example specifies that the message text in NEWMSG.EXE supplements the existing system messages.
