Yes
Set the ``Yes'' flag on, the ``No'' flag off. This command is a utility command, and is being used by several other commands. When input from this command, or its friend, No is required, a prompt is shown in the message area of the display. For example:
Hit Yes to accept, No to cancel.
Great care must be taken if multiple commands are active that wait for a Yes or No. They will be affected in the order that appears in the active command line of the display. The leftmost command will receive the Yes or No.
