token number
token number. The number used by a subsystem to identify each kind of token that it
defines. The token type and the token number together form the token code.
token-oriented. Said of a programmatic interface that conveys information as a series of
code-value pairs accessed by code rather than by address or ordinal position. SPI is
used by application programs and subsystems to provide a token-oriented
programmatic interface.
token type. In SPI, a combination of the token data type and token length; part of the token
code. In DDL, a special definition (using the TOKEN-TYPE statement) that the DDL
compiler will translate into an SPI token type.
token value. The value assigned to a token.
unconditional token. A token that is always present in a particular event message. See
also conditional token and NonStop internal token.
upward compatibility. The ability of a requester to operate gracefully with a server of a
higher revision level. In this case, the requester is upward-compatible with the server,
and the server is downward compatible with the requester. See also downward
compatibility.
version compatibility. The ability of a requester and server of different revision levels to
operate gracefully together.
version number. A 16-bit integer representation of a Product Version Update (PVU). For
subsystems for the NonStop server, it consists of an uppercase alphabetic character in
its left half and a number in its right half.
warning. A condition, encountered in performing a command or other operation, that can be
significant, but does not cause the command or operation to fail. A warning is less
serious than an error. See also error
.
