Resident Four Function Calculator
Ver. 4.8
This is an IBM PC or compatible Terminate and Stay Resident
program that emulates a four function calculator. After it
is loaded into memory by typing "ffc" at the DOS prompt,
it can then be used by pressing Ctrl-F1. It displays what
looks like a normal handheld calculator on screen, with the
results of your calculations displayed at the top of the
calculator in regular calculator fashion. The contents of
the screen below it are saved and will be restored when you
press the Escape Key. It will function with almost any soft-
ware in either color or monochrome text mode (80 column).
Use the numeric keypad for entry, along with the +, -, .,
and the = sign for total. The "c" key will clear to the
calculator to zero and the "e" key clears the calculator
to the previous entry or last result the first time it is
pressed, and works like the "c" the next time it is pressed.
The <enter> key also acts as a total key for ease of use.
I have included a version with "en" behind the file name,
indicating a version for the enhanced key board that does
not turn the NUMLOCK key on and off.
Rounding is to nine decimal places, with all trailing zeros
removed.
The result of a calculation may be pasted into an application
below the calculator, such as a spreadsheet or text editors,
database management fields, accounting ledger entries, etc.
The calculator may be called back so that the F10 key can be
pressed again and again, with the cursor at different places
inside an application, allowing a long number to be easily
inserted repeatedly.
The calculator can be moved around the screen by holding a
shift key, or by pressing Num Lock and then the right or
left arrow keys. On the Enhanced keyboard use the seperate
cursor pad and the "en" version of FFC. The calculator will
remain where you left it between uses and will keep a value
intact in the calculator for reuse at the next call of
Ctrl-F1. Movement is five spaces per move.

Resident Four Function Calculator
Ver. 4.8
The most recent modifications to this program improves the
date paste function, which is executed when the calculator
is on screen and F8 is pressed. It will now work reliably
at any time. The Hot - Key was changed to Ctrl-F1 because
of popular demand to free up Alt-F1. Note the more tasteful
onscreen appearence of the calculator metaphor.
For ease of use, you may want to rename the file from FFC48.
COM (or from FFC48-EN.COM) to FFC.COM and replace any earlier
version.
This is a PUBLIC DOMAIN file. Use it as you wish; give it to
anyone freely. Always distribute the complete ARC file intact
or all of the individual files including this document.
Turbo Pascal programmers who would like to build a calculator
such as this into their own applications should download the
file CALCTP.ARC from CompuServe or CALCTPU.ARC from GEnie and
various BBS's around the U.S. This file contains the needed
code to build the calculator into an application with full
control of the colors, keyboard type, and wait for retrace
to reduce snow on some systems. The source is available from
me for $60.00. The calculator engine is in a UNIT file for TP4
and is an INCLUDE file for TP3. Contact me directly for CALCTPU
.ARC if you cannot locate it.
Enjoy it!
