Many parameters and components require user-supplied information when
you issue an NCP command. For the most part, their syntax follows a
standard set of rules. Exceptions to these rules are documented in the
description of the parameter for which they apply. For the list below,
all numeric values are in decimal and have a range of 0 to 65535 unless
otherwise specified.

All underscores found in parameters must be replaced with spaces
when parameters are used in NCP commands.

a string of up to 39 alphanumeric and hyphen characters.
Currently, VAX/VMS systems do not use this string for access
control.

a decimal value in the range 1 to 63 to be specified in the
beginning of the node-spec and separated from the node number by
a period. If you do not specify an area number, the area number of the
executor is used. The default area number for the executor is 1.

a string of characters whose exact syntax is that for a DECnet or
X25 circuit identification.

For DDCMP circuits, the circuit identification is in the
form dev-c-u.t, for example, DMP-0.1.

For Ethernet circuits, the circuit identification is a string in
the form dev-c, for example, UNA-0.

For X25 circuits, the circuit identification is a string of up
to 16 characters beginning with "X25-".

a decimal numeric value

a string of characters consisting of one of the following:

        DECSYSTEM20
        PDP11
        PDP8
        VAX

an identification string consisting of 1 to 16 alphanumeric characters

A string of characters representing the mnemonic name for the device.
Devices supported by DECnet-VAX include the following.

        BNA     CI      DMB     DMC
        DMF     DMP     ISA     MFA
        MNA     QNA     SVA     TT
        TX      UNA

a string of up to 15 decimal digits. See VAX PSI Public Network Information
Cards for the exact format of this parameter on your network.

a starting of 12 hexadecimal digits, represented by 6 bytes separated by
hyphens, for example, AA-00-04-00-AB-04. The string indicates the Ethernet
address. The bytes are ordered from left to right as transmitted
and received on the Ethernet.

a list of event types for a given class in the format
class.type. When specifying an
event list, you may specify only one class; however, you
can specify a range of types by using commas and hyphens,
for example,  4.3-5,7-10. You can use an asterisk wildcard
character in an event list, but only to replace an event type.
For example, 4.*, identifies all event types for class 4 events.

See HELP EVENTS for a list of valid events.

a VAX/VMS file specification string in the following general format:

node-id::device:[directory]filename.type;version

Logical names are permitted. For a file in your current directory,
you need specify only the filename.type portion of the VAX/VMS filename.

Refer to the VAX/VMS DCL Concepts Manual for the format of a VAX/VMS
file specification, and the Guide to VAX/VMS File Applications
for more information of specifying files.

a string of up to 8 hexadecimal digits.

a string of up to 32 hexadecimal digits.

a string of up to 32 characters. If the string includes spaces or tabs,
enclose it within quotation marks.

a string of characters whose exact syntax is that for a DECnet or
X25 line identification. For VAX/VMS the line identification takes
one of the following forms dev-c or dev-c-u, for example UNA-0 or DUP-0.

a decimal numeric value.

For X25 circuits, specifies a 1 to 16 character alphanumeric
identifier that indicates the network to be used.

a numeric value in the range of 1.1 to 63.1023, composed of area number
to the left of the period followed by a node number to the right
of the period. If the area number is not supplied the area number of the
executor is used. The default area number is 1.

either a node-name or a node-address.

a string of up to 6 alphanumeric characters containing
at least one alphabetic character.

a node-name or node-address followed by optional access
control information as specified for VAX/VMS in the form:

node-id"user-id password account"

The total length of user-id, password, and account must be
less than or equal to 39 characters.

a string of characters consisting of one of the following:

        ROUTING III
        NONROUTING III
        ROUTING IV
        NONROUTING IV
        AREA

a decimal numeric value.

a string of up to 12 printable characters.

a string of up to 39 printable characters.
The total length of user-id, password, and account
must be less than or equal to 39 characters.

a list of VAX/VMS privilege names delimited by space characters.

a decimal numeric value.

a string of alphanumeric characters . The logging console name is a string
in the form TTcnn: (if a terminal) or a VAX/VMS file specification if a
file receives the events. The logging file name is a VAX/VMS file
specification. The logging monitor name is a 1 to 9 character name.
If the string contains spaces or tabs, enclose it in quotation marks.

See file-spec for a description of valid VAX/VMS file specifications.

a string of up to 16 characters.

a string of characters consisting of one of the following:

        SECONDARY LOADER
        TERTIARY LOADER
