to me it looks looks simpler to get properly into unix (and variants) - just
one of those things i've been meaning to do but never gotten around to it.

mind you, work that i *have* done with *nix (linix and AIX mostly) have
always been pleasantly appealing ;-) but then again, just about anything's
a fresh change from big-fat MS overkill <sigh>.

OK! i'm gonna get cracking on that as soon as i get a chance.

wow i feel like i just discovered lazarus reef! ;-)

thanks again,
