| Explanation
|
AG
| Activation Group
| A partitioning of resources within a job. An activation group
consists of system resources (storage for program or procedure variables,
commitment definitions, and open files) allocated to one or more
programs.
|
API
| Application Programming Interface
| A functional interface supplied by the operating system or by a
separately orderable licensed program that allows an application program
written in a high-level language to use specific data or functions of the
operating system or licensed program.
|
ANSI
| American National Standards Institute
| An organization consisting of producers, consumers, and general interest
groups, that establishes the procedures by which accredited organizations
create and maintain voluntary industry standards in the United States.
|
ASCII
| American National Standard Code for Information Interchange
| The code developed by American National Standards Institute for
information exchange among data processing systems, data communications
systems, and associated equipment. The ASCII character set consists of
8-bit characters, consisting of 7-bit control characters and symbolic
characters, plus one parity-check bit.
|
CICS(R)(R)
| Customer Information Control Service
| An IBM licensed program that enables transactions entered at remote work
stations to be processed concurrently by user-written application
programs. The licensed program includes functions for building, using,
and maintaining databases, and for communicating with CICS on other operating
systems.
|
CL
| Control Language
| The set of all commands with which a user requests system
functions.
|
DBCS
| Double-Byte Character Set
| A set of characters in which each character is represented by 2
bytes. Languages such as Japanese, Chinese, and Korean, which contain
more symbols than can be represented by 256 code points, require double-byte
character sets. Because each character requires 2 bytes, the typing,
displaying, and printing of DBCS characters requires hardware and programs
that support DBCS. Four double-byte character sets are supported by the
system: Japanese, Korean, Simplified Chinese, and Traditional
Chinese. Contrast with single-byte character set.
|
DDM
| Distributed Data Management
| A function of the operating system that allows an application program or
user on one system to use data files stored on remote systems. The
systems must be connected by a communications network, and the remote systems
must also be using DDM.
|
DDS
| Data Description Specifications
| A description of the user's database or device files that is entered
into the system in a fixed form. The description is then used to create
files.
|
EBCDIC
| Extended Binary-Coded Decimal Interchange Code.
| A coded character set consisting of 256 eight-bit characters.
|
EPM
| Extended Program Model
| The set of functions for compiling source code and creating programs on
the iSeries system in high-level languages that define procedure calls.
|
FIPS
| Federal Information Processing Standard
| An official standard to improve the utilization and management of
computers and data processing in business.
|
HLL
| high-level language
| A programming language whose concepts and structures are convenient for
human reasoning; for example, C, COBOL, and RPG. High-level
languages are independent of the structures of computers and operating
structures.
|
ICF
| Intersystem Communications Function
| A function of the operating system that allows a program to communicate
interactively with another program or system.
|
ILE
| Integrated Language Environment
| A set of constructs and interfaces that provides a common runtime
environment and runtime bindable application programming interfaces (APIs) for
all ILE-conforming high-level languages.
|
I/O
| Input/Output
| Data provided to the computer or data resulting from computer
processing.
|
LVLCHK
| Level Checking
| A function that compares the record format-level identifiers of a file to
be opened with the file description that is part of a compiled program to
determine if the record format for the file changed since the program was
compiled.
|
ODP
| open data path
| A control block created when a file is opened. An ODP contains
information about the merged file attributes and information returned by input
and output operations. The ODP only exists while the file is
open.
|
ODT
| Object Definition Table
| A table built at compile time by the system to keep track of objects
declared in the program. The program objects in the table include
variables, constants, labels, operand lists and exception descriptions.
The table resides in the compiled program object.
|
OPM
| original program model
| The set of functions for compiling source code and creating high-level
language programs on the iSeries system before the Integrated Language
Environment (ILE) model was introduced.
|
OS/400
| Operating System/400
| The iSeries operating system.
|
PEP
| program entry procedure
| A procedure provided by the compiler that is the entry point for an ILE
program on a dynamic program call. Contrast with user entry
procedure.
|
SDA
| Screen Design Aid
| A function of the Application Development ToolSet for iSeries licensed
program that helps the user design, create, and maintain displays and
menus.
|
SEU
| Source Entry Utility
| A function of the Application Development ToolSet for iSeries licensed
program that is used to create and change source members.
|
SQL/400
| Structured Query Language/400
| An IBM licensed program supporting the relational database that is used
to put information into a database and to get and organize selected
information from a database.
|
UEP
| user entry procedure
| The entry procedure, written by an application programmer, that is the
target of the dynamic program call. This procedure is called by the
program entry procedure (PEP). Contrast with program entry
procedure.
|
UPSI
| User Program Status Indicator switch
| An external program switch that performs the functions of a hardware
switch. Eight switches are provided: UPSI 0 - 7.
