Mark Habersack and I are in the midst of working on a TSR that will
implement the LFN 21h API under DOS 6.0/7.0. After completing that,
we will go on to write a VXD that will implement it under WinNT (all
versions). This should make many DJGPP users reluctant to move to NT
willing to do so, and the TSR for DOS 6/7 might me a powerful thing to
offer to prospective programmers. Anyone interested in it (once
completed) please email me (locke AT mcs DOT net) or Mark
(grendel AT ananke DOT amu DOT edu DOT pl). If you want to offer your assistance in
testing or programming also please email one of us!
