"This little trick" may go away, but old DOS programs that used it
won't. If you are still running "legacy" DOS programs (say, of
mid-1980s vintage) that you didn't write yourself, cutting out the FCB=
line in config.sys (or even cutting the default value from 16 down to 3
as someone recommended) to "save" the negligible amount of memory
involved is foolish. IIRC, that is where this thread started :-).
