IEEE 802.5
IEEE 802.5. A Local Area Network protocol suite commonly known as Token Ring. A
standard originated by IBM for a token passing ring network that can be configured in a
star topology. Versions supported are 4 Mbps and 16 Mbps.
implicit library. A library supplied by HP that is available in the read-only and execute-only
globally mapped address space shared by all processes without being specified to the
linker or loader. See also TNS system library and public library.
implicit library import library (imp-imp). See import library.
implied user library. A method of binding TNS object files that have more than 16 code
segments. Segments 16 through 31 are located in the user code (UC) space but are
executed as if they were segments 0 through 15 of the user library (UL) code space.
This method precludes the use of a user library. Binder now supports 32 segments of
UC space concurrently with 32 segments of UL code space, so the implied user library
method is not needed in new or changed TNS applications.
import. To refer to a symbol definition from another loadfile. A loadfile imports a symbol
definition when it needs a data item or function having that symbolic name.
import control. The characteristic of a loadfile that determines from which other loadfiles it
can import symbol definitions. The programmer sets a loadfile’s import control at link
time. That import control can be localized, globalized, or semiglobalized. A loadfile’s
import control governs the way the linker and loader construct that loadfile’s searchList
and affects the search only for symbols required by that loadfile.
import library. A file that represents a dynamic-link library (DLL) and can substitute for it as
input to the linker. Import libraries facilitate linking on auxiliary platforms (that is, PCs)
where it is inconvenient to store the actual DLLs.
indicator lights. Two light-emitting diodes (LEDs) on a CRU that indicate the status of the
unit. The red or amber indicator light is lit when the unit is not working properly. During
startup, this light can indicate that the unit is not yet functioning. The green indicator
light is lit when the unit has proper power applied. See also light-emitting diode (LED).
input source. The resource from which SCF accepts command input. SCF can accept input
from a terminal or a disk file. The initial input source is determined by the form of the
RUN command used to initiate SCF. At any time during an SCF session, the input
source can be temporarily changed to execute a series of commands from a command
(OBEY) file.
inspect region. The region of a TNS object file that contains symbol tables for all blocks
compiled with the SYMBOLS directive. The Inspect region is sometimes called the
symbols region.
instance. A particular case of a class of items or objects. For example, a process is defined
as one instance of the execution of a program. Multiple processes might be executing
the same program simultaneously. Also, instance data refers to global data of a
program or library. Each process has its own instance of the data.
