LOGOUT

Terminates an interactive terminal session.

Format

LOGOUT


Description

You must use the LOGOUT command to end a terminal session. Under most circumstances, if you turn the power off at your terminal or hang up your telephone connection without using the LOGOUT command, you remain logged in.

When you use the SET HOST command to log in to a remote processor, you generally need to use the LOGOUT command to end the remote session.


Qualifiers

/BRIEF

Prints a brief logout message (process name, date, and time) or a full logout message (a brief message plus accounting statistics).

/FULL

Requests the long form of the logout message. When you specify the /FULL qualifier, the command interpreter displays a summary of accounting information for the terminal session. The default qualifier for a batch job is /FULL.

/HANGUP

/NOHANGUP

Determines, for dialup terminals, whether the phone hangs up whenever you log out. By default, the setting of the /HANGUP qualifier for your terminal port determines whether the line is disconnected. Your system manager determines whether you are permitted to use this qualifier.

Examples

#1

$ LOGOUT
  GILLINGS    logged out at 05-JUN-2001 17:48:56.73
      

In this example, the LOGOUT command uses the default brief message form. No accounting information is displayed.

#2

$ LOGOUT/FULL
  GUZMAN      logged out at 05-JUN-2001 14:23:45.30
Accounting information:
Buffered I/O count:       22     Peak working set size:     90
Direct I/O count:         10     Peak virtual size:         69
Page faults:              68     Mounted volumes:            0
Charged CPU time: 0 00:01:30.50  Elapsed time:      0 04:59:02.63
Charged vector CPU time: 0 00:00:21.62
 
      

In this example, the LOGOUT command with the /FULL qualifier displays a summary of accounting statistics for the terminal session.


MACRO

Invokes the VAX MACRO assembler to assemble one or more assembly language source files (the default on VAX) or invokes the MACRO-32 compiler for OpenVMS Alpha to compile VAX assembly language source files into native OpenVMS Alpha object code (the default on Alpha).

The /ALPHA qualifier causes the MACRO command to invoke the MACRO-64 assembler if it is installed on Alpha.

The /MIGRATION qualifier causes the MACRO command to invoke the compiler on Alpha.


Format

MACRO filespec[,...]


Parameter

filespec[,...]

Specifies an assembly language source file to be assembled. If you specify more than one file, separate the file specifications with either commas (,) or plus signs (+). File specifications separated by commas cause the MACRO assembler to produce an object file (and, if indicated, a listing file) for each specified file. File specifications separated by plus signs are concatenated into one input file and produce a single object file (and listing file).

You cannot include the asterisk (*) and the percent sign (%) wildcard characters in a file specification. For each file specification, the MACRO command supplies a default file type .MAR or .MAR64. The MACRO assembler creates output files of one version higher than the highest version existing in the target directory.


Description

The MACRO command invokes the VAX MACRO assembler to assemble one or more assembly language source files (the default on VAX) or invokes the MACRO-32 compiler for OpenVMS Alpha to compile VAX assembly language source files into native OpenVMS Alpha object code (the default on Alpha).

The qualifiers to the MACRO command serve as either command (global) qualifiers or positional qualifiers. A command qualifier affects all the files specified in the MACRO command. A positional qualifier affects only the file that it qualifies. All MACRO qualifiers except the /LIBRARY and /UPDATE qualifiers are usable as either command or positional qualifiers. The /LIBRARY and /UPDATE qualifiers are positional qualifiers only.

See the qualifier descriptions for restrictions.

For a complete functional description of the VAX MACRO assembler directives, refer to the VAX MACRO and Instruction Set Reference Manual. For a complete functional description of the MACRO-32 compiler for OpenVMS Alpha, refer to OpenVMS MACRO-32 Porting and User's Guide.


Qualifiers

/ALPHA

The /ALPHA qualifier cannot be used with the /UPDATE qualifier.

On Alpha, invokes the MACRO-64 assembler for OpenVMS Alpha (if installed on the system). For a description of the assembler, refer to the MACRO--64 Assembler for OpenVMS AXP Systems Reference Manual.

/ANALYSIS_DATA[=filespec]

/NOANALYSIS_DATA (default)

Controls whether the VAX MACRO assembler creates an analysis data file for the OpenVMS Source Code Analyzer (SCA), and optionally provides the file specification.

By default, the assembler does not create an analysis data file. If you specify the /ANALYSIS_DATA qualifier without a file specification, the assembler creates a file with the same file name as the first input file for the MACRO command. The default file type for analysis data files is .ANA. When you specify the /ANALYSIS_DATA qualifier, you can control the defaults applied to the output file specification by the placement of the qualifier in the command line.

/CROSS_REFERENCE[=(function[,...])]

/NOCROSS_REFERENCE (default)

Controls whether a listing is produced of the locations in the source file where the specified function (or functions) is defined or referenced. If you specify only one function, you can omit the parentheses.

You can specify the following functions:
ALL Cross-references directives, macros, operation codes, registers, and symbols
DIRECTIVES Cross-references directives
MACROS Cross-references macros
OPCODES Cross-references operation codes
REGISTERS Cross-references registers
SYMBOLS Cross-references symbols

Because the assembler writes the cross-references to the listing file, you must specify the /LIST qualifier with the /CROSS_REFERENCE qualifier. If you specify no functions in the /CROSS_REFERENCE qualifier, the assembler assumes the default value of /CROSS_REFERENCE=(MACROS,SYMBOLS). The /NOCROSS_REFERENCE qualifier excludes the cross-reference listing.

/DEBUG[=option]

/NODEBUG (default)

Includes or excludes local symbols in the symbol table or traceback information in the object module. You can replace the /ENABLE and /DISABLE qualifiers with the /DEBUG and /NODEBUG qualifiers when you use the appropriate DEBUG and TRACEBACK options. The /DEBUG or the /NODEBUG qualifier overrides debugging characteristics set with the .ENABLE or .DISABLE assembler directives.

You can specify one or more of the following options:
ALL Includes in the object module all local symbols in the symbol table, and provides all traceback information for the debugger. This option is equivalent to /ENABLE=(DEBUG,TRACEBACK).
NONE Makes local symbols and traceback information in the object module unavailable to the debugger. This option is equivalent to /DISABLE=(DEBUG,TRACEBACK).
SYMBOLS Makes all local symbols in the object module available to the debugger. Makes traceback information unavailable to the debugger. This option is equivalent to /ENABLE=DEBUG and /DISABLE=TRACEBACK together.
TRACEBACK Makes traceback information in the object module available to the debugger and local symbols unavailable to the debugger. This option is equivalent to /ENABLE=TRACEBACK and /DISABLE=DEBUG together.

If you specify no options to the /DEBUG qualifier, it assumes the default value of /DEBUG=ALL.

/DIAGNOSTICS[=filespec]

/NODIAGNOSTICS (default)

Creates a file containing assembler messages and diagnostic information. If you omit the file specification, the default file name is the same as the source program; the default file type is DIA.

The asterisk (*) and the percent sign (%) wildcard characters are not allowed in the file specification.

The diagnostics file is reserved for use with Compaq layered products, such as the VAX Language-Sensitive Editor (LSE).

/DISABLE=(function[,...])

/NODISABLE

Provides initial settings for the functions disabled by the .DISABLE assembler directive. You can specify one or more of the following functions:
ABSOLUTE Assembles relative addresses as absolute addresses.
DEBUG Includes local symbol table information in the object file for use with the debugger.
GLOBAL Assumes undefined symbols to be external symbols.
SUPPRESSION Suppresses listing of unreferenced symbols in the symbol table.
TRACEBACK Provides traceback information to the debugger.
TRUNCATION Truncates floating-point numbers (if truncation is disabled, numbers are rounded).
VECTOR Enables the assembler to accept and correctly process vector code.

If you specify only one function, you can omit the parentheses. If you specify no functions in the /DISABLE qualifier, it assumes the default value of /DISABLE=(ABSOLUTE,DEBUG,TRUNCATION,VECTOR). The /NODISABLE qualifier has the same effect as not specifying the /DISABLE qualifier, or negates the effects of any /DISABLE qualifiers specified earlier in the command line.

/ENABLE=(function[,...])

/NOENABLE

Provides initial settings for the functions controlled by the .ENABLE assembler directive. You can specify one or more of the following functions:
ABSOLUTE Assembles relative addresses as absolute addresses.
DEBUG Includes local symbol table information in the object file for use with the debugger.
GLOBAL Assumes undefined symbols to be external symbols.
SUPPRESSION Suppresses listing of unreferenced symbols in the symbol table.
TRACEBACK Provides traceback information to the debugger.
TRUNCATION Truncates floating-point numbers (if truncation is disabled, numbers are rounded).
VECTOR Enables the assembler to accept and correctly process vector code.

The /NOENABLE qualifier has the same effect as not specifying the /ENABLE qualifier, or negates the effects of any /ENABLE qualifiers specified earlier in the command line. You can specify one or more of the functions listed in the description of the /DISABLE qualifier. If you specify only one function, you can omit the parentheses. If you specify no functions in the /DISABLE qualifier, it assumes the default value of /ENABLE=(GLOBAL,TRACEBACK,SUPPRESSION).

/LIBRARY

/NOLIBRARY

Positional qualifier. The /LIBRARY qualifier cannot be used with the /UPDATE qualifier.

The associated input file to the /LIBRARY qualifier must be a macro library. The default file type is MLB. The /NOLIBRARY qualifier has the same effect as not specifying the /LIBRARY qualifier, or negates the effects of any /LIBRARY qualifiers specified earlier in the command line.

The assembler can search up to 16 libraries, one of which is always STARLET.MLB. This number applies to a particular assembly, not necessarily to a particular MACRO command. If you enter the MACRO command so that more than one source file is assembled, but the source files are assembled separately, you can specify up to 16 macro libraries for each separate assembly. More than one macro library in an assembly causes the libraries to be searched in reverse order of their specification.

A macro call in a source program causes the assembler to begin the following sequence of searches:

  1. An initial search of the libraries specified with the .LIBRARY directive. The assembler searches these libraries in the reverse order of that in which they were declared.
  2. If the macro definition is not found in any of the libraries specified with the .LIBRARY directive, a search of the libraries specified in the MACRO command line (in the reverse order in which they were specified).
  3. If the macro definition is not found in any of the libraries specified in the command line, a search of STARLET.MLB.

/LIST[=filespec]

/NOLIST

Creates or omits an output listing, and optionally provides an output file specification for it. The default file type for the listing file is .LIS. The asterisk (*) and the percent sign (%) wildcard characters are not allowed in the file specification.

An interactive MACRO command does not produce a listing file by default. The /NOLIST qualifier, present either explicitly or by default, causes errors to be reported on the current output device.

The /LIST qualifier is the default for a MACRO command in a batch job. The /LIST qualifier allows you to control the defaults applied to the output file specification by the placement of the qualifier in the command line. For more information on entering output file qualifiers, refer to the OpenVMS User's Manual.

/MIGRATION

The /MIGRATION qualifier cannot be used with the /UPDATE qualifier.

On Alpha, invokes the MACRO-32 compiler for OpenVMS Alpha to compile one or more VAX MACRO assembly language source files into native OpenVMS Alpha object code.

For a complete description of the MACRO-32 compiler for OpenVMS Alpha, refer to OpenVMS MACRO-32 Porting and User's Guide.

/OBJECT[=filespec]

/NOOBJECT

Creates or omits an object module. It also defines the file specification. By default, the assembler creates an object module with the same file name as the first input file. The default file type for object files is .OBJ. The asterisk (*) and the percent sign (%) wildcard characters are not allowed in the file specification.

The /OBJECT qualifier controls the defaults applied to the output file specification by the placement of the qualifier in the command line. For more information on entering output file qualifiers, refer to the OpenVMS User's Manual.

/PREPROCESS_ONLY[=filespec]

/NOPREPROCESS (D)

Causes the assembler to perform only the actions of the preprocessor phase and writes the resulting processed text out to a file.

The filespec defaults to the name of the primary source file. The default file type is .ASM.

/SHOW[=(function[,...])]

/NOSHOW[=(function[,...])]

Provides initial settings for the functions controlled by the assembler directives .SHOW and .NOSHOW.

You can specify one or more of the following functions:
CONDITIONALS Lists unsatisfied conditional code associated with .IF and .ENDC MACRO directives.
CALLS Lists macro calls and repeat range expansions.
DEFINITIONS Lists macro definitions.
EXPANSIONS Lists macro expansions.
BINARY Lists binary code generated by the expansion of macro calls.

If you specify more than one function, separate each with a comma and enclose the list in parentheses. If you specify no functions in the /SHOW qualifier, it increments the listing level count; the /NOSHOW qualifier decrements the count in similar circumstances. Because these qualifiers contribute to the listing file, you must also specify the /LIST qualifier when you use them. If you do not specify the /SHOW qualifier, the MACRO command assumes a default of /SHOW=(CONDITIONALS,CALLS,DEFINITIONS). If you specify only one function, you can omit the parentheses.

/UPDATE[=(update-filespec[,...])]

/NOUPDATE

Positional qualifier. The /UPDATE qualifier cannot be used with the /ALPHA, /LIBRARY, or /MIGRATION qualifier.

Updates the input file it qualifies by using the SUMSLP batch editor and the specified update file or files. By default, the assembler assumes that the update file has the same file name as the input source file and a file type of .UPD. You cannot include the asterisk (*) and the percent sign (%) wildcard characters in the file specifications. If it cannot find a specified update file, the assembler prints an informational message and continues the assembly.

If you specify only one update file, you can omit the parentheses. If you specify more than one update file, the assembler merges the contents into a single list of updates before applying the updates to the source file.

The /NOUPDATE qualifier has the same effect as not specifying the /UPDATE qualifier, or negates any /UPDATE qualifiers specified earlier in the command line. The input source file and update files are not changed by the update operation. The effects of the update appear in the compiled output. If you specify the /LIST qualifier with the /UPDATE qualifier, the assembler writes an audit trail of the changes to the listing file.


Examples

#1

$ MACRO/LIST  CYGNUS, LYRA/OBJECT=LYRAN + MYLIB/LIBRARY
      

In this example, the MACRO command requests two separate assemblies. Using MAR as the default file type, MACRO assembles CYGNUS.MAR to produce CYGNUS.LIS and CYGNUS.OBJ. Then it assembles LYRA.MAR and creates a listing file named LYRA.LIS and an object module named LYRAN.OBJ. The default output file type for a listing is .LIS.

The command requests the search of the MYLIB library file in the current directory for macro definitions.

#2

$ MACRO  ORION
      

MACRO assembles the file ORION.MAR and creates an object file named ORION.OBJ. Executing the command in a batch job causes MACRO to create a listing file named ORION.LIS.

#3

$ MACRO  ALPHA/LIST+MYLIB/LIBRARY-
_$ + [TEST]OLDLIB/LIBRARY + []BETA
$ PRINT ALPHA
      

MACRO concatenates the files ALPHA.MAR and BETA.MAR to produce an object file named ALPHA.OBJ and a listing file named ALPHA.LIS. The command line requests the search of libraries MYLIB.MLB (in the current default directory) and OLDLIB.MLB (in the directory [TEST]) for macro definitions. When macro calls are found in BETA.MAR, MACRO searches the libraries OLDLIB, MYLIB, and the system library STARLET.MLB, in that order, for the definitions.

The PRINT command prints the listing file ALPHA.LIS.

#4

$ MACRO  DELTA+TESTLIB/LIBRARY, ALPHA+MYLIB/LIBRARY
      

MACRO requests two separate assemblies. MACRO searches TESTLIB.MLB and the system library STARLET.MLB for macro definitions when macro calls are found in DELTA.MAR, and searches MYLIB.MLB and the system library STARLET.MLB for macro definitions when macro calls are found in ALPHA.MAR.


MAIL

Invokes the Mail utility, which is used to send messages to other users of the system.

For more information about the Mail utility, refer to the OpenVMS User's Manual or online help.


Format

MAIL [filespec] [recipient-name]


MERGE

Invokes the Sort/Merge utility, which combines 2 to 10 similarly sorted input files and creates a single output file. Note that input files to be merged must be in sorted order.

For more information about the Sort/Merge utility, refer to the OpenVMS User's Manual or online help.


Format

MERGE input-filespec1,input-filespec2[,...] output-filespec


MESSAGE

Invokes the Message utility, which compiles one or more files of message definitions.

For more information about the Message utility, refer to the OpenVMS Command Definition, Librarian, and Message Utilities Manual or online help.


Format

MESSAGE filespec[,...]


MONITOR

Invokes the Monitor utility, which monitors classes of systemwide performance data at a specified interval.

For more information about the Monitor utility, refer to the OpenVMS System Management Utilities Reference Manual or online help.


Format

MONITOR [/qualifier[,...]] classname[,...] [/qualifier[,...]]


MOUNT

The Mount command (MOUNT) is used to make a disk or magnetic tape available for processing.

Format

MOUNT device-name[:][,...] [volume-label[,...]] [logical-name[:]]


Parameters

device-name[:][,...]

Specifies the physical device name or logical name of the device on which the volume is to be mounted. On a system where volumes are not connected to HSCs (hierarchical storage controllers), use the following format:
ddcu:

The dd describes the device type of the physical devices used. For example, an RA60 disk drive is device type DJ, and an RA80 or RA81 disk drive is device type DU. The c identifies the controller, and the u identifies the unit number of the device.

On a system with HSCs, use one of the following formats:

node$ddcu:
allocation-class$ddcu:

If your devices are dual ported to HSCs, use the allocation-class format. For example, $125$DUA23 represents an RA80 or RA81 disk with unit number 23. The disk's allocation class is $125$. The c part of the format is always A for HSC disks. TROLL$DJA12 represents an RA60 disk with unit number 12. The device is connected to an HSC named TROLL. Refer to OpenVMS Cluster Systems for more information about naming conventions.

Device names can be generic so that if no controller or unit number is specified, the system attempts to mount the first available device that satisfies those specified components of the device names. If no volume is physically mounted on the specified device, MOUNT displays a message requesting that you place the volume in the device; after you place the volume in the named drive, MOUNT then completes the operation.

If you specify more than one device name for a disk or magnetic tape volume set, separate the device names with either commas or plus signs. For a magnetic tape volume set, you can specify more volume labels than device names or more device names than volumes.

volume-label[,...]

Specifies the label on the volume.

The number of characters allowed in a label depends on the type of device, as follows:
Device Type Number of Characters
in Label
Magnetic tape 0-6
Files-11 disk 1-12
ISO 9660 disk 1-32
OpenVMS requires disk volume labels to be unique in the first 12 characters within a given domain. For example, disks mounted by different members of the same group using the /GROUP qualifier must be unique. However, disks mounted in different domains, such as one mounted using the /GROUP qualifier and one mounted privately, can use the same volume label.

If you mount an ISO 9660 volume using the /SYSTEM or /CLUSTER qualifier, and the volume label is not unique within the first 12 characters, you must supply an alternate volume label using the qualifier /OVERRIDE=IDENTIFICATION. If you choose this option, then Mount verification is disabled for the device.

In addition, if a volume is part of a volume set and the first 12 characters of the volume-set name are the same as the first 12 characters of the volume label, a lock manager deadlock will occur. To avoid this problem, you must override either the volume label (by using the /OVERRIDE qualifier) or the volume-set name (by using the /BIND qualifier).

If you specify more than one volume label, separate the labels with either commas or plus signs. The volumes must be in the same volume set and the labels must be specified in ascending order according to relative volume number.

When you mount a magnetic tape volume set, the number of volume labels need not equal the number of device names specified. When a magnetic tape reaches the end-of-tape (EOT) mark, the system requests the operator to mount the next volume on one of the devices. The user is not informed of this request; only the operator is informed.

When you mount a disk volume set, each volume label specified in the list must correspond to a device name in the same position in the device name list.

The volume-label parameter is not required when you mount a volume with the /FOREIGN or /NOLABEL qualifier or when you specify /OVERRIDE=IDENTIFICATION. To specify a logical name when you enter either of these qualifiers, type any alphanumeric characters in the volume-label parameter position.

logical-name[:]

Defines a 1- to 255-alphanumeric character string logical name to be associated with the volume.

If you do not specify a logical name, the MOUNT command assigns the default logical name DISK$volume-label to individual disk drives; it assigns the default logical name DISK$volume-set-name to the device on which the root volume of a disk volume set is mounted. Note that if you specify a logical name in the mount request that is different from DISK$volume-label or DISK$volume-set-name, then two logical names are associated with the device.
