system.
system. All the processors, controllers, firmware, peripheral devices, software, and related
components that are directly connected together to form an entity that is managed by
one HP NonStop™ Kernel operating system image and operated as one computer.
system name. A C-series term that identifies a system on a network. A system name
always begins with a backslash character. A system name in a C-series system serves
the same purpose as a node name in a D-series system.
system procedure. A procedure supplied by the operating system.
takeover point. Location of the FORTRAN instruction that immediately follows the last
stack CHECKPOINT statement. The FORTRAN run-time library implicitly executes a
stack checkpoint when a program executes an OPEN or CLOSE statement that
specifies the STACK = 'YES' option specifier.
TNS. HP computers that support the HP NonStop™ Kernel operating system and that are
based on complex instruction-set computing (CISC) technology. TNS processors
implement the TNS instruction set. Contrast with TNS/R.
TNS/R. HP computers that support the HP NonStop™ Kernel operating system and that are
based on reduced instruction-set computing (RISC) technology. TNS/R processors
implement the RISC instruction set and are upwardly compatible with the TNS system-
level architecture. Systems with these processors include most of the HP NonStop™
servers. Contrast with TNS.
target file. The output object file produced by the Binder.
TNS object code. The TNS instructions that result from processing program source code
with a TNS language compiler. TNS object code executes on TNS and TNS/R
systems.
TNS object file. The object file created by a TNS compiler. The file contains TNS
instructions and other information needed to construct the code spaces and the initial
data for a TNS process.
upper 32K-word area. The upper half of the user data segment.
user data segment. A data segment in which your program stores global and local data
and a run-time stack; and in which the FORTRAN run-time library stores its data.
user library. A logically distinct part of the HP NonStop™ Kernel operating system that
consists of procedures that the operating system can link to a program file at run time.
