     PANE SECTION

     The "pane" section (located on the right of the subform) is
     where most actual input of parameter information for a pro-
     cessing routine takes place.  When a specific routine is
     selected from the Guide Pane, the corresponding Pane section
     appears with required and optional parameters which may be
     entered/changed/selected for that routine.

     Text Selections
          "Text selections" are provided for entering string,
          integer, float, and logical values; as well as input
          and output filenames.  Typically these appear as narrow
          rectangular boxes in which the required information is
          entered by positioning the mouse cursor on the box and
          typing.

     Sliders
          For numerical values, optional "sliders" may be used to
          enter a value between predefined limits.  To use, posi-
          tion the mouse cursor on the gray band, hold down the
          middle button and move the mouse horizontally, releas-
          ing when at the desired level.

     Filenames
          Names for input/output files may be typed in or, or
          alternately, selected from a "file browser".  Clicking
          on a filename prompt will bring up a browser window
          containing a list of files in the current directory.  A
          filename may be selected from the browser by clicking
          on the desired name.  A different directory may be
          accessed either by clicking on a subdirectory name (or
          ../ to back up) or by typing it in directly in the
          space at the bottom of the browser.

          Filenames for intermediate results are typically NOT
          typed in, but generated by Cantata when the glyphed
          routines are connected into a program flow graph.  (See
          'SAVE FILE(S)' under Cantata Workspace Help for a
          description on how Cantata assigns names to temporary
          files.)

     Logicals
          Logical values are distinguished by elliptical buttons
          (if supported) which toggle between two alternate
          choices when clicked on.  For example: "Yes/No",
          "True/False", "On/Off", etc.

     Optional Selections
          "Optional" parameters are prefaced by a small box.
          When selected, the box is highlighted, meaning the
          parameter value is used.

     Toggles and Mutually Exclusive Groups
          Text selections may be grouped together so that only
          ONE of the group may be selected at a time.  For "Tog-
          gles" one and only one of the listed options must be
          selected.  For "Mutually Exclusives" one of the listed
          options may be selected or an alternative typed in.

     Action Buttons
          For most situations, it is necessary for the user to
          enter several text selections before initiating any
          action.  In the gather and execute mode, the user first
          enters all the required parameters, then clicks the
          mouse on an "action button" to register the values and
          perform the desired operation.

     Live Text Selections
          If, however, only one text selection input is needed,
          it may be "live" as indicated by a stylized <cr> arrow
          that appears to the right of the parameter input box.
          For such "live" text selections, the desired action is
          initiated by the user entering the required value and
          then hitting the carriage return.
