run-time data unit (RTDU)
run-time data unit (RTDU). Region of an object file used to store NonStop SQL source and
object code.
run-time environment. The services provided by run-time library routines and data objects
(data blocks and pointers) to a program at run-time.
run-time library. A collection of routines that supports requests for services such as I/O and
heap management, math and string functions, exception handling, and error reporting.
secondary entry point. The location where a code block can be accessed through a PCAL
instruction. Only FORTRAN and TAL routines allow secondary entry points. Secondary
entry points have distinct names.
shared run-time libraries (SRL). A library that allows run-time linked libraries to contain
global variables. Binder commands support shared global data between applications
and library files. SRLs are replaced by DLLs in TNS/E.
single-language program. A program in which all routines are written in the same
programming language.
small memory model. A program attribute that specifies that the program’s heap is
allocated in the user data segment.
source file. A file that contains source text such as data declarations, statements, compiler
directives, and comments. The source file, together with any source code read in from
other source files by SOURCE directives, compose a compilation unit that you can
compile into an object file.
sublocal data. Data that you declare within a subprocedure; identifiers that are accessible
only from within that subprocedure.
Symbol region. See Inspect region.
system. The processors, memory, controllers, peripheral devices, and related components
that are directly connected together by buses and interfaces to form an entity that is
operated as one computer.
TAL. See Transaction Application Language (TAL).
TNS/R. The HP computers that support the HP NonStop Operating System and that are
based on reduced instruction set computing (RISC) technology. TNS/R processors
implement the TNS/R instruction set and maintain application compatibility with TNS
processors. The term TNS/R can refer to the instruction set, the architecture, or the
processors.
TNS/R instruction. A 32-bit, register-oriented RISC machine instruction defined as part of
the TNS/R environment. TNS/R instructions are implemented by the RISC chip of a
TNS/R processor. These instructions execute on TNS/R systems but not on TNS
systems.
