Scrolling Calculator
""""""""""""""""""""
I created the Scrolling Calculator because I got tired of having to start
over each time I made an error keying in a long list of standard calculator
entries. The Scrolling Calculator allows the user to edit his or her entries
along the way. You can even insert-copy an existing number by using Ins Line
and then double clicking another entry, and finally, entering an operator.
There is a rudimentary online help screen providing the basics. Experiment
with the calculator to learn more.
Please note that entries are made in a "postfix" manner. In other words,
the number is entered first, then the operator. For example, if the result
(shown under the list of entries) is 15.25 and you want to add 3.75, you would
enter 3.75+. The new result would become 19. The next entry you make would
act upon this new result. So if you entered -2.25*, the result would become
-42.75. Remember, on the computer keyboard that * is for multiplication (x)
and / is for division (wait... I can't seem to find the division key on my
keyboard).
Limitations
-----------
A mouse IS required. You can make entries without a mouse, but it is not
possible to edit the list of entries without one in this version of the
program. You may also use the tab key to go from command button to command
button but the order in which each command button becomes focused will follow
no logical sequence.
It is possible to enter some REALLY BIG numbers when Decimals is set to
Freeform. However, conversions back to a fixed number of decimals may give
inaccurate results. Decimal conversions from more decimals to less may not
retain precision accuracy.
This program is NOT guaranteed against error. I may NOT be held
responsible for any mental or bodily injuries caused by using this program.
This program is freeware and may be distributed freely, but never sold.
Please keep this Readme text along with any distributions.
If you have any suggestions or questions concerning the Scrolling
Calculator program (or if things just generally don't seem to add up), please
send GEnie MAIL to J.DREW8 or CompuServe MAIL to 73557,3232. Thanks.
