DFS3954 TAKEOVER OCCURRED--REENTER THE LAST INPUT (/FORMAT MAY BE NECESSARY)

Explanation
 This message is issued when the former alternate
system (now the active system) informs the terminal user that system
takeover has completed. It also indicates the action that the user
must take to continue the session.
The last input entered before
the takeover has been lost. The input could be data, a PA key, a PF
key, or a clear key.

System action
 Processing continues.

Programmer response
 Enter the /FORMAT command
to get the last format. If the next input generates unexpected output,
enter PA2.
