Thanks. I look forward to seeing the .ini's and rc.local, etc. I come at 
it the other way around. I know Linux/Mac OS X/FreeBSD quite well, but 
know next to nothing about VMS (I know a bit about VAX because of its 
relationship to PDP-11, which I've been studying pretty relentlessly). I 
have a hobbyist license for OpenVMS, but I'm unclear if that's the same 
OS you are referring to?
