ProMATHeus is a copyrighted product designed to assist you by solving
simple and complicated calculations of all types.  It differs from
old-fashioned calculators (and their PC-based mimics)--it works like
you think.  Named variables have replaced memories, equations are
remembered and can interact, and functions can be defined easily.

Designed by a professional mathematician and actuary, ProMATHeus is a
powerful tool for users ranging from the beginning algebra student to
the advanced engineering or scientific professional.  This is because
it can be shaped easily to fit the computational needs of each indi-
vidual.  Libraries of custom functions can be created thereby trans-
forming ProMATHeus to be used with any discipline: finance, mathemat-
ics, engineering, statistics, surveying, navigation, etc.

Required Registration-------------------------------------------------

After extensive development, it is now being released under the
shareware concept.  If, after trying it, you would like to continue
using ProMATHeus, you must register your usage with a $15 donation
sent to:
                    Mark D. Brissman
                    Blarney Stone Software
                    2510 Blarney Stone Lane
                    Bloomington, IL 61704

As a registered user, you will receive a complete, printed instruction
manual with examples, formulas, and hints for users of all levels and
abilities.  You will also be receiving notices of future releases.

In addition, registered users who donate $25 or more will receive
ProMATHeus PLUS.  This enhanced version contains a full complement of
internal logical, statistical, conversion, and other functions.
Further, it has two powerful features which operate on the functions
you have defined: Solve and Integrate.  ProMATHeus PLUS is an
easy-to-use yet powerful calculation assistant for the student or
professional!  See the instructions for details.
General Description--------------------------------------------------

All input is entered at the ??: prompt in several possible forms:

[algebraic expression]
     The expression is evaluated and the result is displayed.  If
     variables are used, the expression is re-evaluated with each
     subsequent operation (signified by ).

[variable] = [algebraic expression]
     As above, with result being assigned to the variable.

[function name] ( [var],[var],... ) = [algebraic expression]
     Function is defined by the algebraic expression which can only
     use variables named in the function variable list.  These
     variables are for the definition only and are not retained.

     Custom functions can be solved for any of their variables and
     graphed using ProMATHeus.  See instructions for details.

[command]
     ProMATHeus command as defined below.
Commands--------------------------------------------------------------

  restart           = erase all functions, variables, and formulas.
  quit              = save to PROMATH.DAT and end ProMATHeus
  save filename     = save current setup without quit
  nosave            = quit ProMATHeus without updating PROMATH.DAT
  get filename      = get new setup from disk
  del # #-# #       = delete list or range of equation numbers
  fdel # # #        = delete list of function numbers
  clear var var     = set list of variables to --unknown--
  erase var var     = delete list of variables
  <esc>             = toggle display menus
  <F1>              = this help message
  <F2>              = display internal functions
  <F3>              = display current ProMATHeus options
  <F10>             = print
  copy # or fcopy # = copy formula or function for editing

There are also a number of system commands which control ProMATHeus
options.  See instructions.

Scroll active menu: <up>, <down>, <F4> (left), <F5> (right).
Input notes-----------------------------------------------------------

  Operators are:   =  +  -  *  /  and ^(power)
