character set. (1) A defined collection of
characters. (2) An attribute that specifies the
symbol set to use for a character string.
CICS. Customer Information Control System.
clipping. Eliminating those parts of the picture
that are outside the viewing window. Also known
as scissoring.
CMS. Conversational monitor system.
color convergence procedure. The method of
"sharpening" the edges of colored, displayed
information. The procedure permits accurate
aligning of the primary colors (red, green, and blue)
that produce other colors on the screen.
configuration. (1) (TC97) The arrangement of a
computer system or network as defined by the
nature, number, and chief characteristics of its
functional units. More specifically, the term
configuration may refer to a hardware
configuration or a software configuration. (2) The
devices and programs that make up a system,
subsystem, or network.
control unit terminal mode (CUT mode). (l)
The way that your work station is attached to the
IBM 3274 Control Unit, during customization, that
allows only one host session. (2) A method of
operation that allows one logical terminal.
coordinates. Values that specify a position in
space.
Copy. The work station function that allows you
to copy alphanumeric data between windows. You
can copy into any window except the personal
computer window, or copy from one area to another
within the same window except in the personal
computer window.
correlation. The processing of segments to
determine if any parts of the picture they define lie
within the pick window that is set.
cursor. A movable locator.
cursor-movement keys. The arrow keys that can
move the screen cursor. You use the black
cursor-movement keys, in the right-hand
control-keys area, for host computer applications
and for work station control mode; you use the blue
cursor-movement keys in the numeric keypad for
personal computer applications. When you are
browsing, the keys move the data in the window;
when you are changing the size of a window, they
move the borders of the window; when you are
copying, they move the cursor to mark the source
and the target area.
Customer Information Control System (CICS).
An IBM program product that enables transactions
entered at remote terminals to be processed
concurrently by user-written application programs.
It also includes facilities for building, using, and
maintaining data bases.
customization. (1) The process in which the
Graphics Control Program is adjusted to match your
work station and the way you want to use it. (2)
The process of adapting the IBM 3274 Control Unit
to meet the requirements of your work station.
customized system diskette. A diskette, for your
work station, on which files from the Graphics
Control Program diskettes have been copied during
the customization procedure.
CUT mode. Control unit terminal mode.
data stream. All data transmitted through a
channel in a single read or write operation.
default.
(1)
A value that is assumed when none
has been specified. (2) An alternative value,
attribute, or option that is assumed when none has
been specified.
DFT mode. Distributed function terminal mode.
digitizer. A device for converting text or a picture,
printed on paper, into a digital representation.
diskette. A flexible magnetic disk, permanently
enclosed in a semi-rigid protective jacket and used
for storing data.
diskette drive. A device in the system unit that
stores information in, and retrieves information
from, removable diskettes.
distributed function terminal mode (DFT
mode)- (1) The way that your work station is
attached to the IBM 3274 Control Unit, during
customization, that allows up to four concurrent
host sessions. (2) A method of operation that allows
multiple concurrent logical terminal sessions.
DOS. Disk Operating System.
dragging. (1) (TC97) In computer graphics, moving
all or part of a display group in a display space in
such a way that the group continuously follows the
pointer as though it were attached. (2) Moving part
of a picture continuously through a series of
positions tracked by the work station user.
