IDD Menu Facility › Using Menu Facility Screens › Message Display and Field Highlighting

Message Display and Field Highlighting

The IDD menu facility displays messages and highlights fields in response to the use of a screen.

Message Display

Messages are displayed on the message line. They:

• Request that additional information be supplied
• Inform you about the next required action
• Confirm the results of current processing
• Indicate why information has not been processed

Field Highlighting

Highlighting is used in conjunction with a message to reference a related field on the screen. The IDD menu facility highlights fields that have been modified or those that are in error. Screen names and the cursor position are also highlighted.

Error Display Screen

When the menu facility returns a message that appears to be truncated, you can request the Error Display screen by typing ERRS in the command area. The Error Display screen displays the IDD DDDL syntax that corresponds to the requested entity options; error messages are listed immediately following each line in error. Error messages consist of the message identifier, the line (CARD) number and word that caused the processing error, and the message text.

After identifying the error, you can return to the screen on which the error occurred by pressing the CLEAR key. You can then correct the error and resubmit the entity options to the compiler.
