`Load PROM routines are bootstra
`loaders so the first block of data which
`the user
`uts on his or her autoload
`media is t e standard loader, which the
`IPL PROM loads into RAM on one
`manufacturer's system console interface
`module. The loader then proceeds to
`load the full program.
`IR -— Refers to the instruction re ister that
`holds the current instruction eing de-
`coded and executed by the central
`processor control section.
`It‘ll—Abbreviation for information re-
`trieval language.
`irregularity stroke-edge — A term used in
`optical character recognition referring
`to the deviation ofany point on the edge
`of a character from its stroke edge.
`[SAM —Abbreviaiion for
`Indexed Se-
`quential Access Method. In sequentially
`retrieving indexed records, the order of
`record processin depends on the col-
`lating sequence 0 key values within the
`index (primary or alternate) being used
`for access. One 5 stem simply reads one
`record via the
`rst key in the index,
`turns the corresponding data over to
`the application program, then reads the
`next record via the next key in the
`index. and so on. Thus, sequential ac-
`cess is provided, even though the sys-
`tem is accessing the data in a hysically
`random order. This method 0 retrieval
`is commonly called the indexed sequen-
`tial access method (15AM).
`isochronous—Having a
`regular
`odicity.
`restitution)
`isochronous modulation (or
`—Modulation (or restitution) in which
`the time interval se arating any two sig-
`nificant instants is t eoretically equal to
`the unit interval or to a multiple of the
`unit interval.

`ISO (International Standards Organita-
`tion) endow-«Codes authorized by the
`ISO to represent alphabetic, numeric,
`and special characters.
`item — l. A field or set of fields holding
`related data or information that con-
`cerns an individual object, event, trans-
`action, or operation. 2. The word is
`used in a similar sense to the word file
`and means each of the unit organiza-
`tions of information of which the file is
`com rised. 3. Consecutive fields can be
`com ined to form a larger unit ofinfor-
`mation called an item. Grouping fields
`
`[0 form an item simplifies the manipula-
`tion of related data fields, and mini-
`mizes the number of instruction execu-
`tions re uired to move consecutive
`fields wit
`in the main memory.
`item, addition—An item that
`is to be
`added at a s ecific place to an already
`established
`le. Addition master item
`would be the proper term if the file is a
`master file.
`-
`
`item advance — A technique in the grou -
`ing ofrecords for o crating successtve y
`on different recor s in storage.
`item, data — Sometimes called a datum. A
`specific member of a data set denoted
`by a data element, for instance, Monday,
`the name ofa specific member of the set
`of the days of a week. The week is the
`data element, Monday the data item,
`and 05 could be the data code.
`
`item design — The set or collection of rec-
`ords or fields to compose an item as
`delineated, or the se uence in which
`fields are to be recor ed; the type or
`group of characters to be allocated to
`each field.
`~ item. elementary—In the COBOL sys-
`tem, a data item containing no subordi-
`nate terms.
`
`item, line --- An item of data, in data proc-
`essing,
`that is on the same level as a
`given set ofitems for a iven application
`and which could logica ly be printed on
`the same line on a lprinter page, for in-
`stance, stock num er,
`item, quantity,
`and cost.
`item list, first — Same as indication, group.
`item separation symbol —A control sym-
`bol which indicates beginning of an
`item.
`
`item size —~- I. The magnitude of an item,
`usually expressed in numbers of words,
`characters, or blocks. 2. The number of
`characters in an item.
`iterate — To execute successively a series
`of instructions, for instance, to execute
`repeatedly a loop in a routine until some
`condition is satisfied. An example would
`be to square each value ofN from one
`to ten and accumulate the squared val-
`ues before exiting the loop and continu-
`ing with the program. This is usually
`done with a series of arithmetic or logi-
`cal operations on a digital computer.
`iteration — l. A single cycle of operations
`in a solution algorithm made up of a
`number of such cycles. 2. The technique
