You mean you STILL haven't altered it?

Exclusive on was maybe good for a few things in DOS days, but even then we were coding for multiuser... actually, it's now months past the 20th anniversary of my first network. The "set excl off" is in my startup procedure for just as long (yep, short form, it's that old).
