status. A Compaq procedure completion code that indicates the outcome of a call. This code can assume one of nine values.

storage group. File attributes that provide information about a file and the data stored in it. These attributes are negotiated at association establishment. The storage-group attributes include the following:

•

•

•

•

•

•

•

•

•

•

•

•

Storage account

Date and time of creation

Date and time of last modification Date and time of last read access

Date and time of last attribute modification Identity of creator

Identity of last modifier Identity of last reader Identity of last attribute modifier File availability

File size Future file size

string-significance parameter. A parameter of contents-type. This parameter applies to the semantics of the file transfer. The values of this parameter are fixed, variable, and not-significant. See also maximum-string-length parameter, relaxation, and contents- type parameter.

subdevice. A logical entity maintained by a Compaq subsystem to provide access to a physical connection—that is, to a communications line. There may be one or many subdevices associated with a given line or process. Exactly what constitutes a subdevice differs depending on the subsystem. In OSI subsystems, a subdevice allows communication between a process at a particular OSI layer, such as an FTAM initiator or responder, and the local Compaq OSI server process (TAPS, TSP, or NSP) that provides the services of the next lower layer. Each initiator subdevice handles one association or (at layers below ACSE) one connection. Each responder subdevice handles one attach, which is used to establish an association requested by a remote application.

A Compaq FTAM initiator subdevice is created dynamically when an association is established and usually lasts only as long as the association exists. A Compaq FTAM responder subdevice is created when the responder issues an attach.

subsystem. (1) A term that generally defines the Compaq software or hardware facilities that provide users with access to a set of services and other resources.

(2) In the context of DSM, a program or set of processes that manages a cohesive set of
