Non Terminate & Stay Resident Four Function Calculator
Ver. 7.5
Use the numeric keypad for entry, along with the +, -, .,
and the = sign for total. The "c" key will clear all
entries. The "e" key functions as a clear entry key
and will clear a just entered number and the display the
previous entry or the previous result. The <enter> key
also functions as a total key for ease of use.
The number lock will be turned on for you so that one
can begin use on the numeric keypad directly. A version
is included that will work properly with an enhanced
keyboard. It simply does not turn on the number lock.
It is called CALC75-EN.EXE
I also turned off the irritating cursor during calculator
use, and back on afterwards. The exit key is Esc.
The calculator can be moved around the screen, to
allow one to view numbers under the calculator. The
movement is effected by holding down the shift key and
then pressing the right or left cursor keys. On the
enhanced keyboard, use the seperate cursor pad.
The most recent modifications to this program include
the entension of decimal precision to nine digits and
a more attractive onscreen calculator metaphor.
This is a PUBLIC DOMAIN program. Feel free to share it
with anyone. You may upload it to your preferred BBS's.
Always distribute the entire ARC file or all of the
contents of the ARC file including this document.
Look for an updated version of the RESIDENT calculator
under the name FFC48.ARC
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!
