MW.NETDOS-EXE MW is a molecular weight calculator for DOS. This version has been re-named to make it compatible with Arachne's "netdos" capabilities. Your Arachne browser must have the netdos plug-in installed before this will work. (Go to http://www.glennmcc.org/apm/ ) Just click on mw.netdos-exe. After it downloads, it will run the molecular weight calculator in a full DOS screen. After exiting the molecular weight calculator, you will be returned to Arachne. For a stand-alone molecular weight calculator that runs in DOS and Windows, rename the downloaded file to: mw.exe The documentation for this program is called: mwdoc.com For stand-alone use only, same directory as mw.exe. These programs are copyrighted freeware. Ron Clarke, AUSREG Consultancy (www.ausreg.com).
