Version 2.7 of Molecular Weight Calculator for DOS now available.
New Features: Recognition of isotopes.
Ability to take numbers to a power in the calculator.
Caution statements for possible user mis-entries.
Why is it better than other programs available? First of all it's
free, yet fully functional. I feel it is very powerful, more functional
and more user friendly than other molecular weight programs I've
found over the net. I like it so much that I'm making it available
for others so that they can use it in their research and studies.
Check out the features listed below, and if it sounds useful
to you, just point your Web Browser to http://plains.uwyo.edu/~monroem/
for the latest version.
Also, you can FTP the file from ftp.uwyo.edu in the Pub directory under
the filename mwt2_7.exe.
Finally, you can get the file through gopher at the address
gopher://gopher.phazc.uni-heidelberg.de in the software/msdos/MWT directory,
those this may be an older version.
As a final option, I can mail you a UUEncoded or MIME encoded version
via e-mail; just drop me a line.
FEATURES
-------------------------------------------------------------------------------
Full On-Line Help - Eleven help screens available during program operation.
Smart Case Conversion - The program will automatically convert lowercase
letters to uppercase where appropriate for ease
of entering a formula. Exact case matching and
non-conversion are available too.
Multi-Line Display - Display of up to seven formulas with their
molecular weights simultaneously.
Percent Composition - Percent composition of up to seven formulas.
Parentheses Are Allowed: (CH3)3CH2CH3
Handles up to 4 layers of embedded parentheses.
Hydrates or other appended compounds are allowed: FeCl3-6H2O
Many abbreviations for common parts of compounds, including amino acids.
See full list below.
PhCl = C6H5Cl
HOac = CH3COOH
*NEW*
Isotopes are now recognized using the following notation:
^13C is Carbon-13
C6H5^18OH is heavy-oxygen (Oxygen-18) labeled phenol
Feature of weighting parts of a compound relative to the other parts.
For example: [.2Na]Cl would have a weight of 0.2*22.989768+35.4527=40.0507
or NaCl-[.5H2O] would have a weight of:
22.989768+35.4527+0.5*(2*1.00794+15.9994)=67.4501
Percent Solver mode for finding the value of "x" in a compound that
satisfies user-specified percent composition requirements.
Built in calculator that understands operator precedence:
4*5-2*3 = 14
(23.43-2.64*3)/6 = 2.585
*NEW* 2+2^4 = 18
Optional display of time during program operation.
Accuracy of the final digit of the molecular wt. and percent composition.
Capability to set optional features at the command line when starting
the program.

About the Author
I am an undergraduate chemistry major at the University of Wyoming
in Laramie, Wyoming. I plan to attend graduate school and aim to
obtain a doctorate in chemistry. I taught myself to program in BASIC on
an Apple //c (with 128 Kb of Ram and no hard disk) in 1986 during
6th grade. Since then, I have updated to GW-Basic, then QuickBasic v4.5
and now QuickBasic v7.1 for DOS. I am familiar with C, and, though I
know it is much faster than QuickBasic, I stick with QuickBasic since
I am much more comfortable with it. With Windows 95 (and beyond) now
out, I realize that my text-based program will probably also die out,
but I will stand by it based on its speed and simplicity. I hope to
convert the program to Windows-based C++ or Visual Basic some day, but
that will not be until Fall 1996 at the earliest.
