Attribute Handling for 6500-Series Terminals
Attribute Handling for 6500-Series Terminals
The following table shows how SCREEN COBOL handles multiple attributes for 6500-
series terminals.
USE FOR SCREEN RECOVERY Statement
The USE FOR SCREEN RECOVERY statement is entered in the Declaratives portion
of the Procedure Division. It identifies a procedure to restore the terminal display
should an error occur while the specified base screens are active. USE FOR SCREEN
RECOVERY clause is invoked when there are terminal or communication errors,
processor failures, or terminal suspensions. See the Compaq NonStop™ Pathway/iTS
TCP and Terminal Programming Guide for a list of errors that invoke the USE FOR
SCREEN RECOVERY clause. The Declaratives procedure is called automatically only
after the terminal is suspended and restarted with the PATHCOM command RESUME
TERM. Typically, the SCREEN COBOL program displays advisory text on the screen,
and the user must then take corrective action. If no user error recovery is provided in the
SCREEN COBOL program, then the TCP takes its own action on terminal errors.
