You may freely distribute the package as a whole provided no changes are made.

Features
--------
Q.EXE is a command line calculator. That is, you type q and your expression
and after the calculation is done, you are back at the DOS prompt.
Q.EXE plots graphs, solves equations, outputs tables of data, does 
statistics, reads and writes to files and printer. Q knows how to do 
bitwise (64 bits) and logical operations and to change bases (2-36).
And of course it knows simple math like 1+1...Also it includes redefined 
constants with state of the art precision (up to 17 digits).
Results are displayed with 17 digits precision.

Installation
------------

This version will work on 286 and up and is ready for ega/vga.
The program works slowly from diskettes, therefore for good performance 
copy the files to a directory on your hard disk.
For fastest long computations, include a line in your autoexec.bat 
to copy q.exe into a ram drive and include the ram drive in the path. 
The reason is that the program is NOT resident and it reloads every 
time you invoke it. The advantage is that it does not use your memory
after  the calculation is done.

*  README - this file.

*  Q.EXE is the calculator (ver 1.71). 
This version will run on 286 or a higher processors.
For graphics you need a VGA or EGA display. You may use other displays
provided you place the right turbo c++ graphic driver in directory clc
which is in the path.
Q runs from DOS prompt. On 1st run just type q and follow instructions.

*  TUTOR.BAT is a tutorial batch file. Run it to see how Q.EXE works, then
you may edit your own batch files to run complicated calculations.
Q.EXE itself includes many help screens.
During the tutorial some outputs are written to an ASCII files "A" and "C".

*  B is a data file used by tutor.bat


How to use q.exe
----------------

How to use the calculator is described in the help screens and the 
tutorial batch file. Here are some highlights.
The program works as a command line. To do something you enter q and 
an expression separated with a space. e.g. q 1+2 will result in 3 (surprise).
If you type just q or q ? you will be referenced to a list of help screens.
For example q ?u will display a getting started screen, q ?k is a reminder 
of all-key words etc.
As a command line program q.exe may run from a batch file to perform 
sequence of related computations. The accompanying tutorial batch file 
(tutor.bat) is used in this way. You may edit it or write your own batch 
files.
