Components of Screen View

The Screen definition is composed of two parts: the screen header information and the Screen Editor.

Screen View Header Information

The screen header information consists of the name, description, link/format name, screen size and position, help size and position, and the header title location. It also displays the date and time that the screen was last changed and the language code.

Screen Name
Type from 3 to 8 alphanumeric characters for the name of this screen. This field is mandatory.

Characters one and two are the Library name. Characters three through eight are the screen name.

For more information, see Class definition in this document, which provides a file naming convention you may implement.

Link/Format Name
Specifies a 2-character library name followed by a 1 to 6-character link name.

This associates the screen to the link or the format and data files. You can then use this screen for CONNECT SCREEN, Script-IV, and 8INPUT.

Press F2 to lookup the available Link definitions.

If you do not intend to use the screen for data entry or menu selection, a format is not necessary.

The default is the name of the Screen definition.

Description
Type up to 40 alphanumeric characters for the description of this screen. This field is optional.

Screen Window Flag (WF)
Displays a Y if this is a windowed screen. Displays an N if this is a non-windowed screen. All Object-oriented screens are windowed by default.

After Read Method You may use this field only if you have installed OPENworkshop. It contains the name of a developer-supplied method that will be called after each record is read and before it is displayed. Refer to OE.OEACUST as a guide to developing After Read Methods. Type the 8-character name or press F1 (or F2) to select and edit the method. For more information, see the OPENworkhop Reference Manual.

Header Type This field controls the use of the screen description in the window’s top border. It is only available if you have defined this screen as a window.
