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.

1  –  ctxt TxtF

    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.

2  –  parnt TxtF

    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.

3  –  ctxtFil TxtF

    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.

4  –  knownCtxts Form

    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.

4.1  –  knCtxtsFrm ScrLst

    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.

5  –  apply Btn

    The Apply button causes the selected context object to be applied
    to any DECset tools displaying on the same DECwindows display as
    is the Context window. You may also double-click on the context
    in the Context Database Entries field to apply the context. In
    addition to applying this context, any command line qualifiers
    that are in effect are then re-applied to the tool.

    A named context must be saved before a context apply operation is
    initiated.

6  –  save Btn

    The Save button saves the context file shown in the Context File
    field.

    This action saves the current definitions/settings (possibly
    modified via the Settings menu) to the context file indicated
    in the Context File field of the main window. If the value in
    the Context File field has changed since the last Save operation
    for the current context, the DECset Environment Manager writes
    the new file specification to the context database. For a new
    context, the Save menu item ensures that the context is known
    by adding the specified context name and associated context file
    specification to the context database. The DECset Environment
    Manager displays a confirmation dialog box for final approval
    before saving new information in an existing context database
    entry and/or an existing context file. The saving of a context
    will affect other DECset tools displaying on the DECwindows
    display only when that context is subsequently applied.
