ms-dos and hypertext

Unless you can use the ftp command in DOS (or otherwise assign a drive letter to a network location), this is not possible. If you CAN use ftp, then you might use the edit or the echo commands to display the contents of an .html file, since it is simply a plain text file. DOS by itself can't parse a URL, so something like http://www.mylot.com would be meaningless in DOS because (a) it doesn't represent a valid DOS path and (b) it doesn't refer to a file - the actual HTML file which is loaded in a browser is the default 'index.html' or whatever the server specifies.
