Creates a Session Control Application.  A Session Control Application
    entity stores information about an end user that is activated for
    receipt of an incoming connection request when the request contains
    that end user's name in its Destination Name field.

    The following is a required argument:

    o   Application Name

        Simple name to be assigned to the application.

    The following values will be set to false by default.  You can set these
    to true by pushing on their associated toggle buttons so that those
    buttons are in the "on" state (filled in):

    o   Incoming Alias

        Specifies how a particular application responds to incoming connect
        requests directed to the alias node address.  The default is to not
        allow the application to receive incoming connect requests that
        have been directed to the alias node address.

    o   Incoming Proxy

        Specifies whether to honor incoming proxy requests.  The default is
        to ignore requests to invoke proxies on incoming requests.  This
        setting on the Session Control Application entity overrides the
        setting of the same attribute on the Session Control entity.

    o   Outgoing Proxy

        Specifies the default action to execute when the user does not
        explicitly specify whether or not to invoke a proxy.  The default
        is not to invoke the proxy.  This setting on the Session Control
        Application entity overrides the setting of the same attribute on
        the Session Control entity.

    o   Outgoing Alias

        Specifies whether a particular application uses the alias node
        identifier in its outgoing connect requests.  The default is not
        to use the alias node address in its outgoing connect requests.

    o   Node Synonym

        Specifies the default form in which the remote node name is
        passed to the application.  The default is to use the fullname.
        If this toggle is turned on (i.e., Node Synonym is set to true)
        when there is no synonym available, then the fullname is used.

    The following arguments are optional:

    o   Client Name

        Identifies the name of the local user that will be activated upon
        receipt of a connect request containing a destination name
        matching one of the values in the destination names attribute.

    o   User Name

        Identifies the default account under which the application is to
        run.  If this is null, then the system defaults are used to
        select the user.

    o   Image Name

        Filename of a program to be invoked upon receipt of a connection
        request containing an address that matches one of the values
        contained in the set described by the Addresses characteristic of
        the Session Control Application entity.

    o   Incoming OSI TSEL

        The TSEL this image will accept connections for.  This is similar
        to the destination names attribute.  However, applications using
        the access point for in-connection matching do not use DNA
        Session Control protocol.

        The TSEL must be entered as a hex octet, Example: '1234'H

    o   Network Priority

    Press the OK button to create the Session Control Application entity,
    or press the CANCEL button to cancel this operation.  In either case,
    you will return to the main window.
