SCOBOLX
SCOBOLX. The object file for the SCREEN COBOL compiler program. This name is given
in a TACL command to invoke the compiler. See also SCREEN COBOL.
screen. A group of data fields that represent formatted data to be displayed on a terminal.
A screen is defined by a screen description entry in the Screen Section of a SCREEN
COBOL program. There are two types of screen: base screens and overlay screens.
See also base screen, overlay screen, and screen description entry.
SCREEN COBOL. A procedural language developed by Tandem and based on COBOL that
is used to define and control screen displays on terminals and other input/output
devices. SCREEN COBOL allows programmers to write requester programs that
communicate with operator terminals and intelligent input/output devices, and that
send data to server processes that manage application databases. SCREEN COBOL
programs are compiled into pseudocode form by the SCREEN COBOL compiler and
then interpreted by the TCP. See also terminal control process (TCP).
SCREEN COBOL Utility Program (SCUP). A utility that provides control and manipulation
of SCREEN COBOL object files.
screen description entry. A declaration of a base screen, and, optionally, an overlay
screen, in the Screen Section of a SCREEN COBOL program. See also screen, base
screen, and overlay screen.
screen-oriented requester. A SCREEN COBOL requester that sends data from working
storage to the display screen of a terminal by way of screen templates defined in the
Screen Section of the Data Division. Similarly, such a requester receives data from the
terminal into working storage by way of Screen Section templates. It uses ACCEPT
and DISPLAY statements in the Procedure Division to interact with the display
terminals. Standard SCREEN COBOL requesters are screen-oriented. See also
message-oriented requester.
screen overlay area. See overlay area.
screen program. A SCREEN COBOL requester program. See also SCREEN COBOL.
Screen Section. A section in the Data Division of a SCREEN COBOL source program that
describes the types and locations of fields in screens that can be displayed on a
terminal.
SCUP. See SCREEN COBOL Utility Program (SCUP).
SEND operation. In SCREEN COBOL, an operation in which a transaction request
message is sent to a server process and a reply is received back from the server
process. See also server-class send operation.
server. (1) A process or program that provides services to a client or a requester. Servers
are designed to receive request messages from clients or requesters; perform the
desired operations, such as database inquiries or updates, security verifications,
numerical calculations, or data routing to other computer systems; and return reply
