The context specification area is used to display information
    about contexts, and consists of the following fields:

    o  context

    o  parent

    o  context file

    o  context database entries

    The context specification area consists of read-only fields. Use
    the menu bar functions to make changes to any of these fields.

    Context Field
    You can display a context name in the Context field by single-
    clicking on a line in the Context Database Entries field or by
    selecting the New menu item from the File menu.

    Parent Field
    The DECset Environment Manager does not allow a circular
    ancestral chain. If a circular chain is detected, the DECset
    Environment Manager displays an error message dialog box, and
    aborts the operation on that context.

    Context File Field
    If you select an existing context file from the Context Database
    Entries field, the name of the context and the associated
    information is displayed in the read-only Context, Parent, and
    Context File fields.

    For a new context, or one for which you are modifying the
    associated context file specification, you may use the Modify
    Database Entry... menu item from the File menu to bring up a file
    selection widget.

    If any part of the file specification is not supplied; for
    example, the disk name, the corresponding component of your
    current default directory specification is used. If the name
    or the file type is not specified, the name of the currently-
    specified context is used as the file name and .DECSET_CONTEXT is
    used as the file type.

    Context Database Entries Field
    The context names (and some associated information) are retrieved
    from the context database listed in the Context Database Entries
    field of the DECset context window.
