Version 2.87 of Molecular Weight Calculator for Dos now available.

      New Features:  Updated the help files to reflect changes in the 
                     Windows version

    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'm making it available for others so that they can 
use it in their research and studies.  This program is ideal for old
Dos-based computers you may have sitting around the lab.  Note that a
Windows version with added features is also available (see below).


AVAILABILITY
------------------------------------------------------------------------------
    Dos Version (MWT v2.87)

The program is available via the web at http://plains.uwyo.edu/~monroem/ or
at http://www.coast.net/SimTel/msdos/chemstry.html and 
http://www.cdrom.com/simtel.net/msdos/chemstry.html and 
http://www.simtel.net/pub/simtelnet/msdos/chemstry/ in the mwt2_87.zip file.

The program is also available via Anonymous FTP at ftp.coast.net under the 
SimTel/msdos/chemstry/ directory in the mwt2_87.zip file, at ftp.simtel.net
under pub/simtelnet/msdos/chemstry/ in the mwt2_87.zip file, and ftp.ccl.net
under the pub/chemistry/software/MS-DOS/Molecular-Weight-Calculator/
directory in the mwt2_87.exe file.


    Windows Version (MWTWin v3.2)

The program is available via the web at http://plains.uwyo.edu/~monroem/ or
at http://www.coast.net/SimTel/win3/chem.html and
http://www.cdrom.com/simtel.net/win3/chem.html and
http://www.simtel.net/pub/simtelnet/win3/chem/ in the mwt3_2.zip file.

The program is also available via Anonymous FTP at ftp.coast.net under the 
SimTel/win3/chem/ directory in the mwt3_2.zip file, at ftp.simtel.net under
pub/simtelnet/win3/chem/ in the mwt3_2.zip file, and ftp.ccl.net under the 
pub/chemistry/software/MS-WINDOWS/Molecular_Weight/ directory in the
mwt3_2.exe or mwt3_2s.exe files.

    As a final option, I can mail you a UUEncoded or MIME encoded version 
via e-mail; just drop me a line.


Please see my home page for the complete Windows version features list.  In 
short, though, it includes all the of features listed below for the Dos
version, plus:
                     New Windows Interface
                     Modify elemental values (element weight and uncertainty)
                     Edit and save abbreviations and elemental values while
                          program is running
                     Save options as defaults
                     Copy and paste information to/from other Windows programs
                     Unlimited formula length
                     Ability to print results
                     Ability to change the font used to display formulas
                     Mole/Mass Converter
                     Formula Finder
                     Full hypertext help

FEATURES
-----------------------------------------------------------------------------
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	Handles up to 4 layers of embedded parentheses.

For example, (CH3)3CH2CH3 is equivalent to CH3CH3CH3CH2CH3.

Hydrates or other appended compounds are allowed.

For example, FeCl3-6H2O.

User-definable abbreviations	Default abbreviations are included for common
parts of compounds, including amino acids.  See full list.

For example, PhCl = C6H5Cl and HOac = CH3COOH.

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 also available.

Up to 150 user-defined abbreviations can be added.

Isotopes are 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
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.

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.

Capability of printing results.

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, QuickBasic v7.1 for DOS, and now Visual
Basic 3.0 for Windows.  I am familiar with C, and, though I know it is much
faster than Basic, I stick with the various forms of Basic since I am much
more comfortable with the language.  I have also been told that Visual Basic
is easier to learn than Visual C, and, in fact, I taught myself Visual Basic
in two days.
