Pageable Screens

Pageable screens allow menu facility users to submit many source statements or options to the DDDL compiler. Pageable screens are identified by the upper right corner, which displays page and line numbers in the following format:

PAGE page-number LINE line-number

The following is an example of a pageable screen.

Two areas of a Pageable Screen

IDD menu facility pageable screens are divided into two areas:

• Heading and message area
• Specification area

Heading and Message Area

The heading and message area contains a preformatted first line, the command area, and the message line:

• The first line contains the simulated PF-key field, the product name, the release number, the screen title, and the screen name. The screen title identifies the screen; the screen name is a 4-character symbol used to reference the screen.

  Note: The simulated PF-key field is an untitled 2-character field that can be used if the terminal is not equipped with program function (PF) keys. For additional information about this field, see Predefined Control Keys later in this chapter.

• The second line contains an arrow pointing to the command area. The command area can be used to:
  • Move from one screen to another by typing in a screen name.
  • Manipulate the definition in the dictionary or leave the session by entering DDDL top-line commands such as SUSPEND or REPEAT.

  Use of the command area is described in detail under Conducting a Menu Facility Session later in this chapter. For a list of top-line commands, see Top-line Commands.

• The message line prompts you for additional information or actions, indicates that your response has been processed, or explains why information has not been processed. The message line is described in detail in Message Display and Field Highlighting later in this chapter.

Specification Area

The specification area contains screen-specific information according to the type of pageable screen. For example, in a pageable screen that contains text, the specification area is unformatted. In a pageable screen that identifies relationships between two entities, the specification area is formatted with blocks of lines that represent a relationship.

Two Types of Pageable Screens

There are two types of pageable screens:

• Screens that contain text
• Screens that identify relationships between two entities

The following text describes how paging works for each of the two screen types.

Screens that contain text

On these screens, each line of text is considered one line of data. As with online IDD screens, text is typed in freeform style. A column scale at the top of the screen makes formatting easier.

Examples of screens that contain text:

• Comments screen
• Module Source screen

Screens that identify relationships

On these screens, each group of lines that represents an entity is considered one line of data.

Examples of screens that identify relationships:

• Within Systems screen
• Record Elements screen
