                               CALC
                               ----

CALC is a command driven scientific calculator program for IBM-
compatible computers. Because it is command based rather than
graphics based it is particularly suitable for use in conjunction
with speech synthesis systems.

CALC provides a comprehensive set of scientific functions, including
trigonometric and statistical calculations. It has ten general
purpose memories including last result recall, the common constants
built in, unlimited parentheses and is accurate to sixteen digits.

CALC's user interface couldn't be friendlier. Calculations are
entered at the prompt in standard algebraic notation, special
functions being entered with a single keystroke, either a letter,
ALT and a letter or a function key. And with CALC there's no such
thing as a syntax error - the input is checked "on the fly" so if
you try to input anything invalid you get a beep straight away.
Full line editing facilities are provided, and CALC also remembers
every line you type in, so if you want to repeat or modify a
previous calculation just use cursor up to recall the line. And if
you are using a synthesiser and forget where you're up to just hit
the space bar and the current line is re-displayed.

Alternatively, if you need a quick answer, don't bother with the
prompt, just enter your calculation on the CALC command line.

And finally, if you run into difficulties CALC has a full set of
help screens available at the touch of F1.
