- 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!
