The NT Windows systems include additional commands, using the tilde symbol, in the batch file language for setting environment variables to parts of a file path string, such as the name and the file extension. See http://searchwindowsserver.techtarget.com/tip/0,289483,sid68_gci1294869,00.html?int=off&Offer=WCMcplb18 under "variable substitution." See also http://www.rgagnon.com/gp/gp-0008.html It would seem that to someone knowledgeable it would be easy to write a console mode program to provide identical functionality by taking these strings as arguments and parsing them and setting the corresponding environment variable from them. I looked in the shareware sites and came up with zip. I doubted that I had hit the right keywords. I am at a loss to know what to call this functionality. Does anyone know of any such programs?
