Navigating Screens

The IDD menu facility consists of the Master Selection screen and subordinate screens arranged in a hierarchical structure. To implement a definition in the dictionary, you must navigate through the menu facility, choosing the next screen.

Screen Descriptions

The following table shows the names of screens and what can be done from each screen.

Screen	Description
Master Selection screen	This screen is at the top of the IDD menu facility structure. From the Master Selection screen, you can: Transfer to an Entity screen to process a definition Transfer to the Session Options screen or the Display All screen Press CLEAR to terminate the session
Entity screens	These screens identify the entity type and occurrence to be defined. From an Entity screen, you can: Transfer to a subordinate screen to further define the entity occurrence Transfer to another Entity screen to begin another definition Go back to the Master Selection screen
Subordinate screens	These screens complete the entity-occurrence definition. From a subordinate screen, you can: Transfer to a lower level subordinate screen to further define the entity occurrence Transfer to any screen on the same level within the entity occurrence Return to a higher level screen within the same entity occurrence Return back to the current Entity screen or to any other Entity screen to begin another definition

Screen

Description

Master Selection screen

This screen is at the top of the IDD menu facility structure. From the Master Selection screen, you can:

Transfer to an Entity screen to process a definition
Transfer to the Session Options screen or the Display All screen
Press CLEAR to terminate the session

Entity screens

These screens identify the entity type and occurrence to be defined. From an Entity screen, you can:

Transfer to a subordinate screen to further define the entity occurrence
Transfer to another Entity screen to begin another definition
Go back to the Master Selection screen

Subordinate screens

These screens complete the entity-occurrence definition. From a subordinate screen, you can:

Transfer to a lower level subordinate screen to further define the entity occurrence
Transfer to any screen on the same level within the entity occurrence
Return to a higher level screen within the same entity occurrence
Return back to the current Entity screen or to any other Entity screen to begin another definition

More information: For more information on screens, see Descriptions of IDD Menu Facility Screens later in this chapter.

Selecting Screens

You can select screens using any of the following methods:

Enter any character at the underscore that immediately precedes a screen name listed in the screen selection area and press ENTER.
Enter a screen name in the command area and press ENTER.
Press the appropriate global or local control key.
Type the PF-key number in the simulated PF-key field and press ENTER.
Press CLEAR to return to the prior screen.
Note: Returning to the prior screen by pressing CLEAR does not process changes on the current screen. To apply any changes to the definition, be sure to press ENTER before pressing CLEAR.

Considerations for entering a screen name

The following considerations apply when you enter a screen name to select the next screen:

You can request an entity screen by typing the DDDL entity type, rather than the screen name. For example, to access the RECD screen, you can type RECORD in the command area. The alternatives are listed as follows:

Screen name	DDDL Entity-type name
ATTR	ATTRIBUTE
CLAS	CLASS
ELEM	ELEMENT
FILE	FILE
MSGS	MESSAGE
MODU	MODULE
PROC	PROCESS
PROG	PROGRAM
QFIL	QFILE
RECD	RECORD
SYST	SYSTEM
TABL	TABLE
USER	USER
ENTY	Not applicable

To eliminate keystrokes when selecting an entity occurrence, you can do either of the following:
- Type only the first three letters of the screen name or the DDDL entity type. Certain screens, such as PROC or PROG, must be invoked using the first four letters to ensure accuracy. For example, to request the Message Entity screen, type MSG in the command area.
- Type the screen name or DDDL entity type followed by the name of the entity occurrence. For example, to display the DENTAL-CLAIM record, you type REC DENTAL-CLAIM in the command area.
  The entity-occurrence name consists of one parameter; version number or other qualifiers are not acceptable. When more than one entity occurrence exists in the dictionary, the menu facility displays the default version number of the requested occurrence.
