absolute pathname. An Open System Services (OSS) pathname that begins with a
slash (/) character and is resolved beginning with the root directory. Contrast with
relative pathname.
ASSIGN. An HP Tandem Advanced Command Language (TACL) command you can use to
associate a file name with a logical file of a program or to assign a physical device to
logical entities that an application uses.
assign message. Within Subsystem Control Facility (SCF), a message created by SCF for
each ASSIGN command. A new process must request its assign message following
receipt of the startup message. All assign messages set by the SCF ASSIGN
command, plus the ones read from the HP Tandem Advanced Command Language
(TACL) command interpreter, are passed to the new process.
assumed object. The object type or object name specified by a Subsystem Control Facility
(SCF) ASSUME command. If an ASSUME command has been used to establish a
default object type and fully qualified default object name, and if that object type and
object name together refer to a valid object, object-spec can be omitted entirely
from an SCF command, and the command is applied to the object known as the
assumed object.
BACKUP. A utility for the HP NonStop™ servers that creates a backup copy of one or more
disk files on magnetic tape. See also RESTORE.
blade complex. See HP NonStop™ Blade Complex (NSBC).

HP NonStop™ servers. See also millicode.
client. A software process, hardware device, or combination of the two that requests
services from a server. Often, the client is a process residing on a programmable
workstation and is the part of an application that provides the user interface. The

Execution of remote procedure calls is an example of a client application.
