If you are a windows programmer, or just getting started, this
message is for you. I have just completed the development and
testing of a Dynamic Link Library that is sure to make your
computing easier. This DLL contains the eighty-six functions for
trigonometry, calculus and geometry listed above.

For an extremely small fee of only \$7.00, I would be happy to send
you a copy of my DLL-Product software. When you purchase the
software, you will receive the following files on diskette. Those
that are marked as "Redistributable" may be redistributed by you
only in accordance with the terms of the License Agreement that you

MathRdp1.DLL - Redistributable.
RdpMath1.TPU - Redistributable.
RdpMath1.HLP - NOT A REDISTRIBUTABLE.
RdpMath1.TXT - NOT A REDISTRIBUTABLE.

If interested in receiving a complete package of these files,
please send a check or money order for \$7.00 (payable in US funds)
to: Roy D. Pope, Jr., PO Box 720, Mobile, AL 36601. Indicate
RdpMath1 in a note with your payment.

Money order payments will be processed within 24 hours of receipt.
Payment by personal check must clear the bank before being
processed. Sorry, no credit card or COD orders, please.

Why a DLL?
Why not make the library statically linkable?

And, btw, these things are easy to do. I wrote the same thing as your
library, and an astronomical function library, in about 4 hours flat in
Delphi. I could do it in about 2 hours for DOS using assembler, but my
Win32 assembly skills aren't too good yet..

For an extremely small free of only \$0.00 you can get a free library, do
what I did and code your own, or pirate your software. That's the nice
thing about DLLs, they're so *distributable*, and the APIs are easy to
find :)
