If you give me a loader(8) that exports a "version" envi= ronment variable, I'll give the Forth functionality in mere seconds.

Whatever string you export i= nto that environment variable will be displayed on-screen at bottom-right, = right-justified. The code for thew new menu has been committed to HEAD. http://svnweb.freebsd.org/base?view=3Drevision&revision=3D222417 Now... Who wants to make the necessary patch to loader(8) to export $loader_versio= n text? Or maybe a suggestion on another list worth including on this? --=20 Devin _____________ The information contained in this message is proprietary and/or confidentia= l.
