ProMATHeus Plus is a copyrighted product designed to assist in solv-
ing 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 Plus
is a powerful tool for users ranging from the beginning algebra stu-
dent to the advanced engineering or scientific professional.  This is
because it can be shaped easily to fit the computational needs of each
individual.  Libraries of custom functions can be created thereby
transforming ProMATHeus Plus to be used with any discipline:  finance,
mathematics, engineering, statistics, surveying, navigation, etc.

ProMATHeus Plus is the successor to the original shareware version,
ProMATHeus.  This 'Plus' version contains many more features and
represents hundreds of hours of development.  Registration is required
for continued use and it is greatly appreciated!  Please see details
in the manual and at the end of this help.

******************** Automatic Demonstration *************************

ProMATHeus Plus has an automatic facility which demonstrates many of
its features.  Simply type:

                          demo

in the input screen and press <enter>.  It's a good way to get
started.  It should take about ten minutes.

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 Plus.  See instructions for details.

[command]
     ProMATHeus Plus command as defined below.
Commands (screen 1 of 2)----------------------------------------------

Files---------------------
  restart           = erase all functions, variables, and formulas.
  save filename     = save current data without quitting
  nosave            = quit ProMATHeus without updating PMP.DAT or .SET
  get filename      = get previous data/formulas from disk
  saveset filename  = save current session characteristics
  getset filename   = get previous session characteristics
  quit              = save to PMP.DAT & PMP.SET and end ProMATHeus

Copying & Deleting--------
  copy # or fcopy # = copy formula or function for editing

  del # #-# #       = delete list or range of equations by number
  fdel # # #        = delete list of functions by number
  clear var var     = set list of independent variables to --unknown--
  clear             = set all independent variables to --unknown--
  erase var var     = delete list of unused variables
  erase             = delete all unused variables


Commands (screen 1 of 2)----------------------------------------------

Windows-------------------
  graph             = invoke multiple function graphing
  <esc>             = toggle display menus
  <F1>              = this help message
  <F2>              = display internal functions
  <F3>              = display current ProMATHeus options
  <F4>              = scroll left---|
  <F5>              = scroll right  |---active menu scrolled
  <up arrow>        = scroll up     |
  <down arrow>      = scroll down---|
  <F10>             = print

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






Input notes-----------------------------------------------------------

Operators:
  Math      :  +       -       *       /     ^(power)  %(remainder)

  Logical   :  &(and)  |(or)   !(not)  #(exclusive or)

  Comparison:  <       <=      >       >=
               !=(not equal)   ==(equality)

  Variable/function names must start with a letter and may include
  numbers.

  Numbers may be in scientific notation: [sign]##.##e[sign][exponent].

  Any number of parentheses may be used.

  Function definitions may include up to 10 variables.

  Input line limited to 200 characters.

  Up to 200 formulas, functions, and variables can be defined, each.
Required Registration-------------------------------------------------

If you would like to keep a copy of ProMATHeus Plus for your use and
if you have not registered it, you must!  This is a shareware program,
but it is not free.

This program represents many hundreds of hours of work by the author.
The impetus to undertake the project, and to further its development
only comes from the registrations of honest users.  We appreciate your
support.

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 receive the most recent version of the
program if you do not already have it.  Lastly, you will receive
notices of future releases.  To register, print the 'order.me' file,
complete it, and send $25 to:
