Glossary-33
teletex string. An extended alphabet for use in international text communication. In addition
to the standard ASCII character set, the teletex character set includes accents and
umlauts (diacritical marks) applied to Latin characters, as well as a number of special
alphabetical combinations such as IJ ligatures. The teletex character set is based on
CCITT recommendation T.61.
terminal O/R address. An O/R address that identifies a user by a network address and, if
required, a terminal type.
TLAM (HP Tandem LAN access method). An HP NonStop product that implements the
services of the Data Link and Physical Layers for LANs.
TMF (Transaction Management Facility). A data management product that maintains the
consistency of a database and provides the tools for database recovery.
token. In DSM, a distinguishable unit in an SPI message. Programs place tokens in an SPI
buffer using the SSPUT or SSINIT procedures and retrieve them from the buffer using
the SSGET procedure. A token has two parts: an identifying code, or token code, and
a token value. In command and response messages, a token normally represents a
parameter to a command, an item of information in a response, or control information
for the subsystem. In event messages, a token normally represents an item of
information about an event or about the event message itself. See also header token.
token code. In DSM programmatic interfaces, a 32-bit value that identifies a token. A token
code consists of a token type (16 bits) and a token number (16 bits). See also token
number, token type, and token map.
token map. In DSM programmatic interfaces, a structure that contains decoding information
for a DSM extensible structured token. Also, a variable name that refers to an
extensible structured token. The token map includes a token code and a description of
the token value: its fields, the null values of those fields, and the versions of the fields.
A token map defines a structure that might change in some later code version (by the
addition of new fields at the end), and the information in the map allows SPI to provide
compatibility between different structure versions.
token number. In DSM programmatic interfaces, the number used by a subsystem to
identify each DSM token that it defines. The token type and the token number together
form the token code.
token type. In DSM programmatic interfaces, the part of a DSM token code that identifies
the data type and length of the token value. The token type and the token number
together form the token code.
token value. In DSM programmatic interfaces, the value assigned to a DSM token.
Transaction Management Facility. See TMF.
