MO:DCA data. Print data that has been composed into pages. Text-formatting programs such as DCF can produce composed text data consisting entirely of structured fields.

MO:DCA data page. A page of print data consisting entirely of structured fields.

MO:DCA print data set. A print data set consisting entirely of structured fields.

MO:DCA-P.Mixed Object Document Content Architecture for Presentation.

N

nested resource. A resource mapped in an overlay.

O

OS/400. The iSeries operating system.

outline font. A font technology in which the graphic character shapes are represented in digital form by a series of mathematical expressions that define the outer edges of the strokes. The resulting graphic character shapes can be either solid or hollow. Outline fonts can be scaled (sized) to any size. The IBM outline font character sets have a prefix of CZ. Contrast with raster font.

overlay. See electronic overlay.

P

page. A collection of data that can be printed on a physical sheet of paper.

page segment. A resource containing MO:DCA data and images, prepared before formatting and included as part of the input for a print job.

parameter. (1) A variable that is given a constant value for a specified application and that may denote the application. (I) (A) (2) An item in a menu for which the user specifies a value or for which the system provides a value when the menu is interpreted. (3) Data passed between programs or procedures.

pel. See picture element.

physical medium. A physical entity on which information is presented. Examples of physical media are display screens, paper, foils, microfilm, and labels.

picture element. An element of a raster pattern about which a toned area on the photoconductor might appear. See also raster pattern. Synonym for pel.

point. A unit of measurement about 1/72 of an inch; used in measuring the height of a font. Contrast with pitch.

point size. The height of a font in points.

print job. The data that a user submits to PSF for printing.

Print Services Facility (PSF). PSF is a licensed IBM program that manages and controls the input data stream and output data stream required by supported IBM page printers. PSF manages printer resources such as fonts, images, electronic forms, form definitions, and page definitions, and provides error recovery for print jobs.

When printing line data, PSF supports external formatting using page definitions and form definitions. This external formatting extends page printer functions such as electronic forms and use of typographic fonts without any change to applications programs.

printable area. The area on a sheet of medium on which print can be placed.

printer. A presentation device that produces hardcopy output. See presentation device.

processor. In a computer, a functional unit that interprets and executes instructions. (I) (A)

PSF. See Print Services Facility.

R

raster font. A font technology in which the graphic characters are defined directly by the raster bit map. Contrast with outline font.

record format line data. A form of line data where each record is preceded by a 10–byte identifier.

resolution. In computer graphics, a measure of the sharpness of an image, expressed as the number of lines and columns on the display screen or the number of pels per unit of linear measure.

resource. (1) A collection of printing instructions used by PSF in addition to the print data set to produce printed output. PSF resources include coded fonts, font character sets, code pages, page segments, overlays, form definitions, and page definitions. (2) Any source of aid used for performing a task, such as disk storage space, computer processing time, and communication lines.

resource name. The name under which a resource object is stored, the first two characters of which indicate the resource type:

X0-XG,XZ

Coded font

T1

Code page

C0-CG,CZ

Font character set
