Overview

CA ADS control commands are used to pass control during the execution of an application. The execution of a control command terminates the execution of the process that issues the command. A control command can pass control to:

Another dialog
A copy of the same dialog
Another component within the same dialog
A user-written program
Another application function when using the EXECUTE NEXT FUNCTION command

Summary of Control Commands

Control commands are listed in the table below. Each command is presented in alphabetical order after General Considerations.

Command	Purpose
CONTINUE	Terminates the current process, executes the dialog's premap process, and writes a message
DISPLAY	Displays a dialog's map, reexecutes a dialog's premap process, or specifies a message that appears in a map's message field
EXECUTE NEXT FUNCTION	Passes control to the application function associated with a response by means of the control command specified for the response during application compilation
INVOKE	Initiates execution of a lower level dialog in the application thread
LEAVE	Terminates the current application or terminates the current CA ADS session
LINK	Initiates execution of a lower level dialog, creating a nested application structure, or initiates execution of a user program
READ TRANSACTION	Terminates the current process, performs a mapin operation, and selects the next application function or response to be executed (batch only)
RETURN	Initiates execution of a higher level dialog
TRANSFER	Initiates execution of a dialog at the same level as the dialog passing control
WRITE TRANSACTION	Terminates a current process, performs a mapout operation, and passes control within an application (batch only)
