     PROGRAM SUBFORMS

     The Khoros processing programs are typically accessed by
     using the subform buttons which are grouped under general
     categories in menus across the top of the master form.  Each
     subform contains the information for a group of related pro-
     cessing programs available from the Khoros libraries.
     (Alternately, programs may be selected directly by name
     using the `ROUTINES' action button.)

     There are both subform buttons, which when selected give
     direct access to a subform and there are subform menu but-
     tons, which give you access to a group of subforms via a
     pull-down menu.  The default cantata workspace uses all sub-
     form menu buttons.

     Subform Buttons
          Clicking the mouse on a subform button selects the
          corresponding subform which then appears in the
          workspace window, or alternatively an outline of the
          subform will appear for interactive placement if your
          window manager does not auto place.  The subform guide
          pane (see below) lists the programs available on that
          subform.

     Subform Menu Buttons
          The menu buttons on the top of the master form (for
          example, `INPUT SOURCES') provide a pull-down menu of
          related subforms.  To use, position the mouse cursor on
          the category of interest, then press and hold the mouse
          key.  The menu of subforms will "drop down" beneath the
          button.  A specific subform is selected by sliding the
          mouse down until the desired title is highlighted, then
          releasing the mouse button. The corresponding subform
          of programs will then appear.

     Guide Panes
          The guide pane on the left of the subforms presents the
          user with a choice of the available programs on that
          subform.  Selecting a program, presents the pane sec-
          tion (to the right) containing information for that
          specific program.  Once a program has been chosen and
          its parameters specified, the subform must be "glyphed"
          so that it may be connected in a program flow graph.

     Each subform contains `HELP' which provides additional docu-
     mentation on subform usage, as well as a general description
     of the programs on that subform and specific help for each
     program.

     EXTENDING CANTATA

     Cantata is designed to be easily extended into other pro-
     cessing domains.  A user can add new programs by editing the
     User Interface Specification file that specifies cantata's
     subforms.  Please consult Volume II of the Khoros
     Programmer's Manual for more information.
