IBM G544-5774-01 manual Carriage control character. An optional character

C	elements being transmitted, or intended for
	transmission, in character or binary-digit form, using a
carriage control character. An optional character in	defined format.
an input data record that specifies a write, space, or	default. An attribute, value, or option that is assumed
skip operation.
	when none is explicitly specified. (I)
cassette. In a cut-sheet printer, a movable enclosure	DDS. See data description specifications
for paper supply. See also bin.

character. (1) A symbol used in printing. For example, a letter of the alphabet, a numeral, a punctuation mark, or any other symbol that represents information. (2) A byte of data.

coded font. A font library member that associates a code page and a font character set. For double-byte fonts, a coded font associates more than one pair of code pages and font character sets.

code page. A font component that associates code points with character identifiers. A code page also identifies how undefined code points are handled.

code point. A one-byte code representing one of 256 potential characters.

concatenate. (1) To link together. (2) To join two character strings.

concatenated data set. In iSeries, a group of logically connected data sets that are treated as a single data set for the duration of a job step. See also data set.

document. (1) A publication or other written material pertaining to a specific subject or related subjects. (2) In word processing, a collection of one or more lines of text that can be named and stored as a separate entity.

double-byte coded font. A font in which each character is defined by two bytes, of which the first defines a coded font section, and the second defines a code point in that section. Double-byte coded fonts are needed for the support of languages requiring more than 256 graphic characters; two bytes are required to identify each graphic character. Kanji is printed by using a double-byte font. Contrast with single-byte coded font.

download. To transfer data from a processing unit to an attached device such as a microcomputer for processing.

duplex printing. Printing on both sides of a sheet of paper. Contrast with simplex printing.

E

continuous forms. A series of connected forms that feed continuously through a printing device. The connection between the forms is perforated to enable a user to tear them apart. Before printing, the forms are stacked, folded along the perforations. Contrast with cut-sheet paper.

control character. A character that starts, changes, or stops any operation that affects recording, processing, transmitting, or interpreting data (such as carriage return, font change, and end of transmission).

cut-sheet paper. Paper that is cut into separate sheets before it is printed on. Contrast with continuous-forms paper.

D

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.

data set. A named set of records stored and processed as a unit. Synonym for file.

data stream. (1) All information (data and control commands) sent over a data link, usually in a single read or write operation. (2) A continuous stream of data

EBCDIC. Extended binary-coded decimal interchange code.

electronic overlay. A collection of constant data, such as lines, shading, text, boxes, or logos, that is electronically composed in the host processor and stored in a library, and that can be merged with variable data during printing. Contrast with page segment. See also overlay.

enabled. (1) Pertaining to a state of the processing unit that allows certain types of interruption. (2) A condition of the printer (physically selected) in which the printer is available to the host processor for normal work. Contrast with disabled mechanism.

end-user interface. A method by which a customer can obtain the services of a product, for example, coding samples, commands and command lists. Every product does not have an end-user interface; some products provide their services through programming interfaces, some provide services through a command line interface, and others provide their services only to other products.

escape character. The control character X'2BD3' in a text-control sequence that indicates the beginning of the sequence and the end of any preceding text.
