binding
binding. The operation of collecting, connecting, and relocating code and data blocks from
one or more separately compiled TNS object files to produce a target object file.
breakpoint. An object code location at which execution will be suspended so that you can
interactively examine and modify the process state. With symbolic debuggers,
breakpoints are usually at source line or statement boundaries.
In TNS/R or TNS/E native object code, breakpoints can be at any MIPS RISC
instruction or Itanium instruction within a statement. In a TNS object file that has not
been accelerated, breakpoints can be at any TNS instruction location. In a TNS object
file that has been accelerated, breakpoints can be only at certain TNS instruction
locations not at arbitrary instructions; some source statement boundaries are not
available. However, breakpoints can be placed at any instruction in the accelerated
code.
CLUDECS. A file, provided by the TNS CRE, that contains external declarations for CLULIB
functions.
CLURDECS. A file, provided by the native CRE, that contains external declarations for
Saved Message Utility functions, data, and data structure declarations in pTAL.
Common Language Utility (CLU) library. A collection of functions that provide common
services to two or more language products.
Common Run-Time Environment (CRE). A set of services implemented by the CRE
library that supports mixed-language programs. Contrast with language-specific run-
time environment
Common Run-Time Environment (CRE) library. A collection of functions that supports
requests for services managed by the CRE, such as I/O and heap management, math
and string functions, exception handling, and error reporting. C, COBOL, and
FORTRAN run-time libraries call CRE library functions to access resources managed
by the CRE. TAL and pTAL user routines can call CRE library functions to access
resources managed by the CRE.
HP NonStop operating system. The operating system for HP NonStop servers.
CISC. See complex instruction-set computing (CISC).
complex instruction-set computing (CISC). A processor architecture based on a large
instruction set, characterized by numerous addressing modes, multicycle machine
instructions, and many special-purpose instructions. Contrast with reduced instruction-
set computing (RISC)
connection. A path managed by the CRE from a process to a Guardian file. Each
connection is a unique path to the same Guardian file and to the same open of that file.
The CRE manages the connection. The CRE provides connection services for
standard files.
