Version 2.6 of Molecular Weight Calculator for DOS now available.

	New Features:  Able to recognize all 21 amino acids, plus deuterium.
                    Able to edit all elements of a compound during % solving.
                    Displays target values and differences from actual values
                      at end of percent solver routine.
                    Expanded error trapping and on-line explanations.

   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_6.exe.
    Finally, you can get the file through gopher at the address
gopher://gopher.phazc.uni-heidelberg.de  in the software/msdos/MWT directory


                        MOLECULAR WEIGHT CALCULATOR
                             by Matthew Monroe
                      Revision 2.6    January 1996

                 This program is Freeware; distribute freely.


FEATURES
-------------------------------------------------------------------------------
    Full On-Line Help - Nine 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

    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

    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++ some day, but that will not
    be until Fall 1996 at the earliest.
