FlCalc - A programmer's calculator
(C) 1997, 2000 David Rushall
All rights reserved
---------------------------------------------------------
INTRODUCTION
FlCalc is a programmer's calculator with a difference.
Originally written to compliment the Calc application on
my Series 3a as I couldn't find anything I liked that did
what I needed and ported to the Series 5 for the same
reason.
Features include
o 32-bit integer expression evaluation.
o Multiple simultaneous output formats including
decimal, hex and binary.
o ASCII and EBCDIC character tables.
o Multiple memories.
o Repeatable statements.
o Pen-enabled on-screen keypad.
o Copy and paste.
---------------------------------------------------------
INSTALLATION
To install this software on your machine:
1) Close ALL applications on your EPOC device.
If you do not close all applications before
installing the SIS package in the next step
you may have version problems later.
2) Install the main application SIS file:
FlCalc.sis
3) After the Clipboard OPM is installed, a
directory called "Clipboard" will have been
created in the root directory of your machine.
If you do not wish to develop you own
applications using the OPM you can delete this
directory and its contents without affecting the
operation of FlCalc.
4) Finally, look in the "Extras" draw on the machine
for the new "FlCalc5" icon, in the normal manner.
NOTES:
* Please consult the manuals for your device for
details of installing applications packaged in SIS
files. You will require a PC or Mac running your
EPOC connect software (i.e. PsiWin 2 or equivalent)
or the "Add/Remove" icon on the control panel of
your EPOC device. Double-clicking on the SIS file
either on the EPOC device or on the PC/Mac connected
to the EPOC device should do the trick.
* OPMs are special resources that may be shared by
many different applications on the EPOC device. If
these applications do not deliver the OPMs correctly
in the standard SIS files, they may cause problems
with other applications when they are installed, or
even uninstalled. If you find that this application
fails to start after installing or uninstalling
another application, perhaps reporting a missing or
invalid OPM file, please try reinstalling this
application using the instructions above. This
should correct the problem.
---------------------------------------------------------
UNINSTALLING
If you have finished with this software you can remove
the application as follows:
1) Make sure the FlCalc application is not running.
2) Using the "Add/Remove" icon on the EPOC control
panel, remove the "FlCalc5" application.
After you have completed these steps, FlCalc will have
been removed from your machine's memory and "Extras" bar.
---------------------------------------------------------
BASIC USE
In its basic form, FlCalc is simple to use. Simply choose
the application from the Extras bar, enter your
calculation and press Enter.
For example, try...
5+(7-2)
By default, you can enter numbers in decimal or
hexadecimal (other formats are available using special
notation), as indicated by the second button in the
status area (under the input line). To switch between
them, simply tap the button, or choose the appropriate
item from the main menu.
The results of you calculations are displayed in the
large window, with each value being displayed in
multiple formats, e.g. both hexadecimal and binary.
The selection of output format is made using the third
button in the status area, or appropriate menu items.
See the online help file (accessible from the "Tools"
menu within the application) for detailed instructions
for use, including details of operators and advanced
expression syntax.
A summary of operators follows...
BINARY OPERATORS
+ :ADD - add
- :SUB - subtract
* :MUL - multiply
/ :DIV - integer divide
% :MOD - modulus (remainder)
& :AND - logical and
| :OR - logical or
? :OR - logical or
^ :XOR - logical xor
<< :LEFT - shift bits left
>> :RIGHT - shift bits right
UNARY OPERATORS
- :NEG - negative (2's compliment)
~ :NOT - logical not (1's compliment)
# :MIRROR - mirror image of bits
