    27 A window group is associated with a task, i.e. a running application. The 

    28 window group's name encodes four pieces of information for that task:

    29 

    30 the name of the document that the task is handling,

    31 

    32 the task's caption,

    33 

    34 the application specific UID, as eight hexadecimal characters,

    35 

    36 status information for the task, as two hexadecimal characters.
