KMSF
Records in a key-sequenced file can be updated or deleted. Contrast with entry-
sequenced file and relative file.
KMSF. See Kernel-Managed Swap Facility (KMSF).
keyword. A character sequence recognized by a command process.
LDEV. See logical device.
ld utility. A utility that collects, links, and modifies code and data blocks from one or more
position-independent code (PIC) object files to produce a target TNS/R native object
file. See also eld utility and nld utility.
legacy system. An operating system that is not open but from which applications must be
ported or users transferred.
library. A generic term for a collection of routines useful in many programs. An object code
library can take the form of a linkfile to be physically included into client programs, it
can be an OSS archive file containing several linkable modules, it can be a loadfile, or
it can be a system-managed collection of preloaded routines. Source-code libraries fall
outside the scope of this glossary.
library client. A program or another library that uses routines or variables from that library.
library file. See library.
linking. The operation of collecting, connecting, and relocating code and data blocks from
one or more separately compiled object files to produce a target object file.
load. (1) To transfer the HP NonStop™ operating system image or a program from disk into
a computer’s memory so that the operating system or program can run.
local millicode. Emulation millicode routines that are physically copied into each TNS
program code file when accelerated for TNS/E. These are a small and frequently used
subset of the full set of accelerated-mode millicode routines located in the system’s
TNS Emulation Library. The program’s calls to its local copy of these routines are
faster and more compact than DLL calls to the external library.
logical device. (1) An addressable device, independent of its physical environment.
Portions of the same logical device may be located in different physical devices, or
several logical devices or parts of logical devices may be located in one physical
device. (2) A process that can be accessed as if it were an I/O device; for example,
the operator process is logical device LDEVOPR.
logical device number. A number that identifies a configured logical device. A logical
device number can be used instead of a device file name when opening a device file.
logical memory. The portion of virtual memory that can be accessed by any process in
nonprivileged mode.
