TAKE NOTE PRINTING/PROGRAMMERS' CALCULATOR v1.0
Copyright 1990, Take Note Software
If you are at all familiar with calculators you should have
no trouble with this program. The program may be used as an
accessory or as a Gem program (with the extender renamed from
".ACC" to ".PRG"). It has the ability to output to a printer after
each entry/calculation or store these and print them out as a
group.
The calculator uses its own window and as such may be dragged
around the screen to get it out of the way. It is closed or
removed from operation the same manner as any Gem window. The
program is rather memory hungry (using about 100k) because of the
tape function.
TAPE BOX
The box to the right of the calculator is the tape box
which can display a history of 18 operations at a time and hold
999 total. As you exceed the number of displayable operations you
will see the scroll bar at the right of the window reconfigure.
You may use the scroll bar to display any portion of the "tape".
There are five different buttons which affect the tape box.
TAPE OFF - Turn the tape box off.
DEC - See below.
PRINT - Print the entire tape.
CLEAR - Clear the entire tape
SPACE - Insert a blank line in the tape box.
NUMBER FORMATS
There are 6 possible formats that you can display numbers in.
"DEC" decimal, or base 10
"$" decimal, base 10 but in dollars and cents format
which includes truncating to the second decimal
place.
"HEX" hexadecimal, or base 16
"OCT" octal, or base 8
"BIN" binary or base 2
"RT" Running total. This is available only in the
second display.
There are boxes to the right of all three display areas which
control the format of numbers used within. All three will read
"DEC" the first time you use the calculator. You may cycle
through the various formats by clicking on these boxes.
OPERATORS/FUNCTIONS
Besides the standard +,-./,*,^ there are operators and
functions that programmers often use as described briefly below.
These are found to the left of the calculator below the display
boxes.
Below are logical operators which act on a pair of numbers
bit wise.
AND - Logical AND.
NOT - Logical AND NOT.
OR - Logical OR.
XOR - Logical XOR.
Next are the shift and roll functions. They take a number
and shift or roll bits to the left or right. They can operate
using either a "Long" word (32 bits), a "Word" (16 bits) or a
"Byte" (8 bits) (see below). The largest valid argument is
32. Larger numbers are treated as argument MOD 32. See the next
entry.
SHR - Shift bits right.
SHL - Shift bits left.
ROR - Roll bits right.
ROL - Roll bits left.
LONG - The button named "Long" does not initiate an
operation but controls the number of bits used by
the shift and roll functions. You can change between
the three lengths described above by clicking on
this box.
There are two functions for changing individual bits (0 to
31) of a number. If you enter an argument greater than 32 the
result will reflect the argument MOD 32, e.g., 4 BSET 33 gives the
same result as 4 BSET 1. See "MOD" below.
BSET - Set a bit to ON.
BCLR - Set a bit to OFF.
The following functions require no argument and operate
immediately upon the current number, displaying the result.
SIN - The sine of a number.
COS - The cosine of a number.
TAN - The tangent of a number.
ATAN - The arc tangent of a number.
ASIN - The arc sine of a number.
ACOS - The arc cosine of a number.
DEG - Converts radians to degrees.
RAD - Converts degrees to radians.
SQR - The square root of a number.
LOG - The logarithm of x base e.
EXP - The xth power to the base of a number.
These next functions either round or return a portion of the
current number. They also require no argument.
TRUN - Truncate, returning only the whole portion of a
number. This is not rounding as TRUN(1.51)=1 where
ROUN(1.51)=2.
FRAC - Returns only the fractional portion of a number. e.g.
FRAC(1.75)=.75
ROUN - Rounds the current number.
MOD - The last function was added at the last minute and
returns the modulus or remainder of an integer
division. e.g 10 MOD 3=1 or the remainder of 10
divided by 3=1. This function returns only whole
numbers and all input will be rounded.
SEND
To the left of the calculator is a button called "SEND". If
this is selected when you close the calculator, the number shown
in the top display box will be transmitted as a series of
keystrokes. Any application which is monitoring the keyboard
should receive it. This can be handy for sending the results of
a calculation to your word processor. The sent string is padded
on both ends with a space.
PRINTER
You may choose to have the calculator print out operations
and numbers immediately by clicking on the button that is labeled
"Printer". Normally all output will be to the right side of the
paper but if you want to print on narrower paper or are more
comfortable with the calculations to the left, select the button
named "L. Just.". This selection will also affect the tape box
print-out.
KEYSTROKES
All keys on the numeric keypad and regular keyboard follow
their on-screen graphic equivalent. Additional keystrokes are;
F1 - Cycle through the main display box number formats.
F2 - Cycle through the translation display formats.
F3 - Cycle through the tape box formats.
Undo - CE (Clear entry).
Clr/Home - CA (Clear all).
")" on the numeric keypad is the equivalent of "^".
"/" on the keyboard is the equivalent of the on-screen "ö".
"ö" (Ascii code 246) is also sent to the printer. This
character will print as an italic "v" if you're printer is using
the Epson italic character set but is present in most other
standard character sets.
DISCLAIMER
This program has been tested quite a bit but Take Note
Software accepts no liability for damage from its' use or misuse
and makes no claims as to its suitability for any specific
purpose. If you discover any bugs or have any suggestions to make
please feel free to contact us. Please include this read me file
with the program if sharing it with others.
This program has been released to the public domain
and is free. Of course if you find it useful and want to send us
money (maybe 5$? ) we won't argue with you about it. This is a
new concept in software distribution based on guilt called Share-
your-money-with-us-if-you've-got-it-ware which shouldn't be taken
too seriously.

REVISION LOG
V1.1 - 01/06/91
- Large numbers (outside the range -2147483648 to 2147483647)
entered or translated to hex/octal/binary formats no longer crash
the system however these numbers will be automatically displayed
in decimal or floating point no matter what type translation is
selected.
- There is now a choice to print to disk as well as the printer.
The file saved is "TAPE####.ASC" where #### represents the number
of the tape file. The program checks to see if previous tape
files are present and takes the first available number, i.e., if
"TAPE1.ASC" is found the file will be saved as "TAPE2.ASC". The
files are saved to the default directory (the directory booted to
or that the program was run from).
