On the mainframe, the use of 24 bits (or three bytes) to hold addresses of memory. 24 bits can address memory up to 16Mb. This limit is known as the line. Mainframe Express emulates both 24-bit addressing and 31-bit addressing by mapping mainframe-style above and below the line addresses to real 32-bit PC memory addresses.
On the mainframe, the use of 31 bits (or four bytes excluding bit 0) to hold addresses of memory. 31 bits can address memory up to 2Gb. Mainframe Express emulates both 24-bit addressing and 31-bit addressing by mapping mainframe-style above and below the line addresses to real 32-bit PC memory addresses.

An IBM family of display terminals, keyboards, and printers supported via the SDLC or TN3270 protocol. CICS BMS screen mapping support was designed specifically for these devices.
IBM's facility that enables data streams from 3270 terminals to be captured, and transmitted and received, using an alternative interface. The 3270 transaction assumes it is communicating with a real or emulated 3270 terminal.
The 3270 bridge enables you to run 3270-based CICS transactions without a 3270 terminal. Commands for the 3270 terminal are intercepted by CICS and replaced by a messaging mechanism that provides a bridge between the end user and the CICS transaction.
The bridge exit is the interface between an existing 3270-based transaction (or set of transactions) and a client application. It is invoked by CICS whenever a terminal command is issued by the original 3270 transaction.
The 3270 bridge exit program used by all eBiz Transactions is called MER0BRIP. MER0BRIP is provided by Micro Focus as part of the product and must be installed on the mainframe when the Component Generator is installed.
Software that enables a PC to provide a 3270-type user interface to CICS Option. The terminal emulator detects the screen size of the device running it, and passes this to the terminal installation process.

Microsoft's Active Server Pages (ASP) is a server-side scripting environment.
When a Web server receives a request for an ASP file, it processes any server-side scripts contained in the file and builds a Web page to send to the Web browser. As well as server-side scripts, ASP files can contain HTML and calls to COM components that perform a variety of tasks, such as connecting to a database or processing business logic.
A mechanism in some Web servers, enabling Web pages to contain server-side scripts. Such a page, when requested by a browser, is executed by the Web server instead of simply being sent. The scripts should be written to generate valid HTML. The Web server then sends the page to the browser, with the scripts replaced by the generated HTML.
See ASP page.
The scripts can be written in any scripting language supported by the ASP engine in the Web server. The most popular is VBScript, which has a syntax resembling a simplified Visual Basic. Another is JScript. The version of JScript in Netscape Web servers is called JavaScript. (Despite a superficial similarity in syntax, JScript and JavaScript have no connection whatever with the Java programming language.)
Since Active Server Pages is the name of a facility, the term is singular.
ASP and JavaServer Pages (JSP)and can be regarded as equivalent facilities, with ASP being the "Microsoft-world" one and JSP the "Java-world" one.
The window that can currently receive input from the keyboard, distinguished by an emphasized title bar and border.

A (.css) file imposes formatting on an HTML document. CSS style sheets can also be used with XML documents.
An addition to the HTML standard which enables presentation information to be separated from structure in an HTML document. Styles can be attached to HTML elements, through a STYLE attribute on an individual element, a <STYLE>...</STYLE> block which names element types in the head of an HTML document, or through separate .css files. Styles can also be defined as classes in a .css file or <STYLE>...</STYLE> block, and attached to elements through the CLASS attribute.
Stylesheets cascade through a system of precedence, whereby styles in .css files have the lowest precedence, and those declared in a STYLE attribute have the highest.
In Mainframe Express, the data structure that is used to store information about mainframe data sets that are accessed from the PC. It should not be confused with the MVS catalog which also stores data set information, but for mainframe use only. In Mainframe Express, the MVS catalog is emulated (in order to support the CATLG disposition) by means of the Catalog field in the Mainframe Express catalog entries. A value of Yes indicates that the data set is cataloged in the MVS catalog.

An OO COBOL source element which contains the code and data descriptions for a class object (or factory, in ISO 2002 teminology) and its instance objects. It is also known as the class source element. A class consists of nested COBOL source elements, which correspond to class object (factory) and instance object methods. Each class starts with an identifier naming the class and the class from which it inherits. When a class is loaded at run time, the OO run-time system creates the class object (factory).
In Micro Focus OO COBOL, lists all the classes the program is going to use. The Class-Control paragraph is part of the Object Section, in the Environment Division. Each entry links a class name to the filename of the class executable file. The class-names are the object references which the program uses for sending messages to the class object at run time.
The equivalent in ISO 2002 OO COBOL is the Repository paragraph.
If the program itself is an OO COBOL class, the Class-Control paragraph also lists its superclass, and the class itself.
See also: class, class object, object reference, Repository paragraph, and superclass.
In Micro Focus OO COBOL, an object which is a template for the creation of instance objects of the same type. For example, the the OrderedCollection class object creates instances of OrderedCollection. The class object itself does not have the same behavior and methods as the instance objects which it creates.
By analogy, a biscuit cutter is a template for creating biscuits; however, you can't eat a biscuit cutter and you can't stamp a biscuit from another biscuit. In Micro Focus OO COBOL, all the methods and data for a class object and the instance objects which it creates are represented by a class program.
The class object is created at run time when a class is loaded.
The equivalent in ISO 2002 OO COBOL is the factory.
The set of classes supplied with OO COBOL. The root class of the Class Library, Base, implements basic behavior for all classes, and provides a superclass for your own classes. There are also classes to implement collections, exception handlers, CallBacks, and GUI interfaces.
