Glossary-5
local data
local data. Data that you declare within a procedure; identifiers that are accessible only
from within that procedure.
lower 32K-word area. The lower half of the user data segment. The global, local, and
sublocal storage areas.
main routine. The first routine to execute when a program is run. The main routine
determines the run-time environment for a program. It is the routine declared with the
MAIN or PROGRAM keyword.
Master Control Block (MCB). A structure that holds CRE data.
MCB. See Master Control Block (MCB).
mixed-language program. A program that contains source files written in different HP
programming languages.
MIPS RISC instructions. Register-oriented 32-bit machine instructions in the MIPS-1 RISC
instruction set that are native to and directly executed on TNS/R systems. MIPS RISC
instructions do not execute on TNS systems and TNS/E systems.
Contrast with TNS
instructions and Intel Itanium instructions.
Accelerator-generated MIPS RISC instructions are produced by accelerating TNS
object code. Native-compiled MIPS RISC instructions are produced by compiling
source code with a TNS/R native compiler.
MIPS RISC word. An instruction-set-defined unit of memory. A MIPS RISC word is 4 bytes
(32 bits) wide, beginning on any 4-byte boundary in memory.
Contrast with TNS word
and word. See also Itanium word.
native. An adjective that can modify the following: object code, object file, process,
procedure, and mode of process execution. Native object files contain native object
code, which directly uses the MIPS instruction set or Intel Itanium processor
instructions and the corresponding conventions for register handling and procedure
calls. Native processes are those created by executing native object files. Native
procedures are units of native object code. Native-mode execution is the state of the
process when it is executing native procedures.
native-compiled Itanium instructions. See Intel Itanium instructions.
native-compiled MIPS RISC instructions. See MIPS RISC instructions.
native-compiled RISC instructions. See MIPS RISC instructions.
native mode. See TNS/R native mode or TNS/E native mode.
native-mode code. Object code that has been compiled with TNS/R native compilers to run
on TNS/R systems or with TNS/E native compilers to run on TNS/E systems.
