-- MathPad is a general purpose graphing scientific calculator. It uses text input rather than simulating buttons on a hand held calculator. This live scratchpad interface allows you to see and edit your entire calculation.
-- MathPad runs on a Mac Plus or higher with system 6 or system 7.
-- The application file may be installed wherever is convenient. It does not require or create any auxiliary files. It may be handy to create a separate folder for MathPad if you want to use include files or XFun files.
-- The distributed MathPad application has its memory size set at 200K. If you are cramped for memory or if you use MathPad for heavy duty calculations you may want to use the Finder's Get Info... box to change MathPad's memory size.
-- 150K if you never use large files, image, read() or write().
-- 170K if you use advanced features.
-- 200K if you use advanced features, large files and large arrays.
-- >200K if you run out of memory when set at 200K. Huge arrays?
----------- Upgrading to version 2.3 ----------------
-- Existing documents should work fine with version 2.3. See the file "What's New" for a details on how to use the new features.
-- A minor change in the label coordinate system means that old documents with saved plot labels may need to have the label locations adjusted.
-- Since atan2() is now built in, any existing files with definitions for atan2() will have to have those definitions removed.
-- Arrays used in assignment statements must have uniform dimensions.
----------------- Using MathPad --------------------
-- MathPad may be used as a calculator simply by typing in numbers and operators. When the ENTER key is hit, each line is evaluated and the results are inserted into the text.
2*(3+4):14.000
-- MathPad inserts the ":" and the result "14.0". A status line at the bottom of the window will show a "√" to indicate that evaluation is complete. If any problems are encountered, they will be reported in the status line and the cursor will be moved to the problem in the text. You can edit and re-evaluate the text at any time. The RETURN key simply terminates a line. It does not cause any evaluation. The ENTER key is on the numeric keypad (or next to the space bar on powerbook keyboards).
-- MathPad can do much more than act as a simple calculator. The built-in help file (choose Help general from the File menu) gives some examples of more advanced features.
--The file "MathPad.doc" describes the full capabilities of MathPad mainly by giving short examples.
-- The "Examples" folder contains some longer examples and utility functions. These examples show how to implement such things as equation solving, curve fitting, vector calculations and numerical solutions of differential equations.
-- The files "Plotting", "Images", "Datafiles" and "Programming" give some extra detail on these subjects.
