(1) A program statement that specifies an operation to be performed by the computer, along with the values or locations of operands. This statement represents the programmer's request to the processor to perform a specific operation. [OSF]<br />(2) In COBOL, one or more clauses, the first of which starts with a keyword that identifies the instruction. Instructions affect the flow of control, provide services to the programmer, or both.<br />(3) In REXX, one or more clauses that describe some course of action to be taken by the language processor. Instructions may be assignments, keyword instructions, or commands.
Industry:Software
(1) A data set on disk storage that contains queues of messages awaiting transmission to particular terminal operators or to the host system.<br />(2) In PSF, a virtual data set built by the library access system interface (LASI) subcomponent in memory to store error messages for printing at the end of the document.<br />(3) The message data set is used principally to pass messages about the current state of specific resources from the active system to the alternate system. It is also used for the secondary surveillance signals of the active, alternate, or both CICS systems, when the control data set is unavailable for this purpose, either because the last write has not completed yet or because of I/O errors.
Industry:Software
(1) A program that allows an operator to get information from a disk file.<br />(2) A program that runs while the system is in inquiry mode.
Industry:Software
(1) A data set or file stored on MVS, in contrast to the view of the file as seen by the workstation.<br />(2) The Virtual Storage Access Method (VSAM) entry-sequenced data set (ESDS) or key-sequenced data set (KSDS) upon which an alternate index is built.
Industry:Software
(1) A program that causes a computer to act as a workstation attached to another system.<br />(2) A facility of the integration test client that enables the emulation of components and references during module testing. Emulators are either manual or programmatic. See also manual emulator, programmatic emulator.
Industry:Software
(1) A data structure for processing work in which the first element added to the queue is the first element processed. This order is referred to as first-in first-out (FIFO).<br />(2) A line or list of items waiting to be processed; for example, work to be performed or messages to be displayed or transmitted.<br />(3) A WebSphere MQ object to which message queuing applications can put messages, and from which they can get messages.<br />(4) A logical subdivision of the MERVA queue data set used to store the messages associated with a MERVA message-processing function. A queue has the same name as the message-processing function with which it is associated.<br />(5) A sequence with restricted access in which elements can only be added at the back end (or bottom) and removed from the front end (or top). A queue is characterized by first-in, first-out behavior and chronological order.<br />(6) A WebSphere MQ object that holds messages for message queueing applications. A queue is owned and maintained by a queue manager.<br />(7) A constructed and maintained list of items that are waiting to be processed. A collection of data objects with the same name in a Shared Queue.
Industry:Software
(1) A program that controls the operation of a communication controller.<br />(2) A program used for requests and responses exchanged between physical units in a network for data flow control.
Industry:Software
(1) A data type that contains a sequence of bytes that can range in size from 0 bytes to 2 gigabytes less 1 byte. This string does not have an associated code page and character set. BLOBs can contain, for example, image, audio, or video data.<br />(2) A block of bytes of data (for example, the body of a message) that has no discernible meaning, but is treated as one solid entity that cannot be interpreted.
Industry:Software
(1) A program that copies data from a management software system, converts it to IDML, and stores it in books in the discovery library.<br />(2) A component of an IBM product that captures discovery information.
Industry:Software
(1) A data type that contains a sequence of characters (single-byte, multibyte, or both) that can range in size from 0 bytes to 2 gigabytes less 1 byte. In general, CLOB values are used whenever a character string might exceed the limits of the VARCHAR type. See also large object.<br />(2) A character string that contains single-byte characters with an associated code page.
