     FUNCTIONS

     A "function" that was previously saved in ASCII format in a
     file, may be used as input for Xprism2. Numerous operators
     and functions are supported using this method of input.

     To plot a "function" file, fill in the "Filename" parameter
     box with the desired filename (for more information, see the
     help on the Environment Pane), and click on the "PLOT FILE"
     action button.  The information from the "function" file
     will be read in, interpreted as described above, and
     displayed according to the current value of the "plot type"
     toggle.  Either C-style comments /*  */ or a '#' may be used
     to designate comments in the function file.

     The syntax for specifing a function in a file is as follows:
          f(x) = sin(x) *cos(x) + x**2
          x = (-pi, 3.14, 40)
     The "f(x)=" preceding the function is a must.  The range
     must be in the form illustrated. If this form is not fol-
     lowed exactly, the parser will generate an error message.
     The fields for the x range are as follows:
          x = (minimum point, maximum point, number of points)

     For more information on functions and the Khoros expression
     parser, see below.
