Visual Programming Network Editor Control Device

       Disclosed is a method to feed back execution information
and give navigational control in a cluttered visual programming
environment to a user by a convenient, adjustable position, on-screen
device.

      A network editor provides a window onto all or part of a
data-flow diagram for a visual program.  Visual feedback of execution
of modules within the network is given by highlighting the name of
the active module, if present within the window, onto the data-flow
diagram.  Often this window is too small to show all the network and
is obscured by a display window and control panels.  The window can
be scrolled using two independent scroll bars for X and Y movement.

      A device exists for controlling both X and Y movement of a
window in the "APE" visualization system which allows a button to be
moved within a small rectangular area.  The position and size of the
button within the area corresponds to the visible portion of the
data-flow diagram in the network editor window.

      An extension of this device would allow visual feedback of
execution by placing a single tiny coloured rectangle or a small
clock or hour glass icon into the device at a position corresponding
to the position of the active module within the network editor.  The
user can easily observe the general flow of control from modules near
the start of the data-flow diagram to modules near the end.  Modules
