- 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.
-
